This is the first grow for me ever, and im starting to face some problems. There is something wrong with my plants. For any embarrassing use of the English language, keep in mind its not my first language. ;)
First i will give you an overlook of my setup:
/// Growarea - Homebox growtent, 160x80x80 cm or 63x31x31 inches.
/// Light /// 400 W Hps with more than 45 cm distance to the plants.
/// Ventilation - A big fan running on low speed gives the plants fresh air
and 2 small computer fans gives some wind emulation to the plants.
/// Temperature - 26-28 celcius or 78-82 Fahrenheit.
/// Plants Age: About 5-6 weeks in total.
/// Plants Height - About 60cm, one 85cm (23 inches, one 33.5 inches)
/// Strains - Different Indica & Indica/Sativa from Nirvana Seed mix.
/// Pots - 3.5litre
/// Soil - Just some general organic soil mix.
/// PH - Not a clue actually, i have no way to measure it.
/// Nutrients - Just a simple organic mix for flowers used seldom.
/// Watering Frequency: When the top of the soil gets dry, although since
the problem appeared i started watering alot in case of nutrient burn.

Doesn't look so bad from here right? Well, you can see that some plants are alot more yellow then others, and i have the feeling that this problem has just started since it gets worse every day. Especially the problem with brown spots is getting worse.
Both these problem started after i gave my plants nutrients the last time, i use a general biological nutrient mix.
It says on the bottle that it should be well shaken before use,
i completely forgot to shake it the last time, plus i gave them more then i have ever done before.
So when the problems started to appear 2 days later i figured i had burnt them by giving them to much (and maybe an unbalanced mix due to the fact that i didn't shake the bottle)
But after comparing with pictures of nutrient burns, it doesn't look like what im having at all. The case with nutrient burns seem to be that the leafs get burnt on the edges, while my leafs just yellow from the inside and spreads to the outside like something is missing and the plant starts to eat from its own resources by sucking the juice out.
The first problems, yellow leafs:
On some of the plants the leafs are yellowing very rapidly.
And it yellows from the inside and then reaches to the outside of the leaf thru its veins. Of almost all the examples of yellowing leafs i have seen on the internet, its the opposite, the problem starts on the outside and reaches for the inside.
The problem of yellow leafs have spread across all of the leafs on some plants. So its not just the case of the bottom leafs yellowing.
Again refer to the overlook picture.
Examples of this:

http://img214.imageshack.us/img214/2451/dsc00095kc6.th.jpg (http://img214.imageshack.us/my.php?image=dsc00095kc6.jpg)
Here you see in comparison leafs from two different plants.
http://img214.imageshack.us/img214/6429/dsc00108wj1.th.jpg (http://img214.imageshack.us/my.php?image=dsc00108wj1.jpg)
The second problem, brown spots:
Brown spots on many of the yellow leafs, but also occurring on some of the healthier plants more green leafs. Its not the case of spider mites since there is no black spots under the leafs, i have had spider mites in an early stage but managed to defeat them using simple methods, so i know what they look like.
Examples of the brown spots:

looks like it maybe a nitrogen deficiency, and maybe your pH is too low
can you get pH strips and pour some distilled water through your pots until a little bit of water comes out the bottom, then measure the pH of that water?

Ok, i did exactly what you told me, and the stripes shows a pH value of something between 5.6 & 5.9!
This is to low right?
I have a jar with contains a powder of 75% Calcium Carbonate and 25% Magnesium Carbonate, what about using a little of this on the plants?
It is actually to raise the pH-value in humans, but i figure it should work on plants to!

If its a case of nitrogen defiency, would it be bad to use fertilizer i have?
It contains 3% nitrogen, 2% phosphor and 5% potassium oxide
So even if the plants would get nitrogen, it would also get large amounts of potassium oxide as well as an addition of phosphor - could this turn into a new problem of overdosing these?
c-ray
12-14-2007, 11:38 PM
yes you can adjust pH with that by mixing some with the water, but it will probably not all dissolve in water so strain off the water and adjust your water to around 6.3-6.6...try feeding one plant with this water and see what the pH is when it comes out the bottom...should be 6.0-6.5
see how the plant likes the new pH, it is possible that there is enough nitrogen but the pH is too low for the plant to absorb the nitrogen, if you give the plants too much nitrogen the very tips of the leaves will burn
your fertilizer is probably ok for veg and early flower but you should get a new fertilizer for mid flowering, with less nitrogen...in flowering you want an NPK ratio more like 1-2-5
just out of curiousity what is your native language?

"Take a trip, collect seeds, and sold for bucks" sort of thing... My main concern was ecological purity. Some areas of Altai mountains are wasted with rocket fuel flying over Altai from Baikonur.. well, the guy hove nothing to say again except outrage. final: he was banned and his sponsorship ended. I hope sldm is a different person. my nick over olk is peganum.

I would consider the problems generalized, on some plants almost all the leaves are yellow, except for the smallest around the buds. It does not look like they will last, a few has fallen already.
In short heres what i did:
More then a week ago my plants looked fine, i feed them some nutrients, double the amount i have given them before.. And i forget to shake the bottle , so they only got the nutrients that "floats" in the nutrient bottle (its a mix of different)
A few days later, the leafs starts to yellow - i instantly think its a nutrient burn (which it isnt since i have compared pictures of nutrient burns).
So thinking i have give them to much nutrients i start watering like crazy..
Im also a bit lazy (& dumb), so i leave the excessive amounts of water on the floor... and the fan goes off nighttime..
Shortly after some days of over watering to defeat the imaginary nutrient burn - a few leaves starts to get rusty spots... Probably because of a to much moist & damp environment.
The rust gets worse, the plants get more yellow - i come here and ask for help.
And i feel i still dont know what is making the plants leafes yellow!! I will try to feed some more nutrients today (have been waiting for the soil to dry up somewhat), but one of the six plants have a new symptom.... something that looks like nutrient burn!!!! The edges of the top leaves looks nutrient burnt to me.. i will post a picture..
But i want to know what was the problem in the first place? To small pots? (3.5l), to low Ph? (5.6-5.9)
Im just feeling like giving up somewhat, the plants are just whining and i dont know what they want!!

Ok, so i have given them calcium carbonate together with some nutrients and they start to shape up somewhat.
My idea of what happened is now the following 3 things:
1. To low ph, plant cant eat the nutrients. Hungry plants makes sad leaves.
2. Newbie grower overacting over the fact that his green ones have reached puberty and that yellowing is just a natural part so the plant can make way for the sexy stuff.
It seems very clear now, the new small leafs around the buds look very fine, and those will grow to larger leafs, while the first set of leafs during vegetative growth not is needed anymore..
3. The worst problem.. Newbie grover misjudging plant-puberty for nutrient burn and start watering like theres no tomorrow and therefore creating rustspots due to high humidity.
And here is some new taken pictures, as you can see, the spots is most likely the worst problem.
Does anyone know if the rust spots will spread to the clean parts of the plant? But it doesnt seem so, it seems as if the plant reacts by dropping the infected leaf. Lovely smart plants. I love them!
Here is some pictures.

I would consider the problems generalized
this really narrows it down then:) for the most part...:chin:
so Generalized:
basically here are the options..Nitrogen
Stunted light green plants; older leaves yellow in color, followed by drying and browning in advanced stages
and Phosphorus
Stunted abnormally dark green plants usually with petiole angles;
abundant reddish or purplish pigmentation; sometimes chlorosis of older leaves
of those two, of course N deficiency seems most obvious.
I do believe we are looking at deficiency situation. When a plants leaves yellow out..it means that the plant is, in a sense, "eating her reserves", much as someone who is fasting from food will lose weight:shocked: By means of translocaton of nutrients in the plant, they deplete accumulated reserves in an effort to sustain overall growth.
i start watering like crazy..Shortly after some days of over watering
hopefully you flushed the media and reset it with nutrients for the plant fairly quickly. If you were to flush for several days, you would certainly force the plants into the above translocation for sustenance situation. In media culture, weekly maintenance flush and final removal flush are very different 'horses' and don't have the same style at all. Measuring the runoff, and flushing to at or below desired strength has the desired effect of removing the nutes in the media, but also leaves not enough for the plant to feed on. So, reset the media with fresh nutes at the optimal range so they can keep eating.
now as far as the brown spots go, we already know that we have to wet of media, so the plant has a very difficult time getting a happy feed.
If you had bigger pots your media volume would give you more of a buffer against wet dry/cycles..and nutrient accumulation..
were pretty sure we had pH problems, also making it hard for the plant to 'eat happy'..
and that wet room is not helping your plant breathe any..also its a great grounds for mold and bacteria..but were hoping that is not involved..
basically, with plants once the damage is done..its done..the area is sealed off..and the plant recovers by growing new growth to replace it. Once a leaf is yellow, its pretty much not going to turn back to green again.
Hungry plants makes sad leaves sounds like a really smart signature...lol..and is bang on of course.
2. Newbie grower overacting over the fact that his green ones have reached puberty and that yellowing is just a natural part so the plant can make way for the sexy stuff
i would not say that chlorosis, is a necessary function of natural maturation at all..maybe its just the hungry plants make sad leaves..and they are now even bigger and growing faster and hungrier...lol
The worst problem.....start watering like theres no tomorrow
Does anyone know if the rust spots will spread to the clean parts of the plant?
probably not, now that they should be back to healthy production. you did mention..the new small leafs around the buds look very fine and this is the new growth..so thats a great sign.
There is one that differs from the rest, the tallest one seems to be a little troubled by the sun rays no?
If you mean to much lumens..or to light for the plant...no..
imo..fwiw..lol

Hello!
I have faced problem I can't identified.
Two of my RM Vipers has purple stems/veins and pale green/yellow older leaves, oldest pair with a subtle touch of necrosis at the ends.
I have two Accidental Hazes in the same soil and pots and they look normal.
1 litre 100% organic soil, 3 weeks in veg. I'm going to report them into 5 litre pots because I think they outgrow current pots, but I don't think this is the case...

check your room temperature at plant level; should be 77F. get them up off of the cold floor. some strains are more sensitive then others. also i see you have clay? pellets in 1 gal. pots. how much soil? futhurmore check the micro nutrients in that organic soil. with the small amount that you seem to be using i think your plants are starving and using stored nutrients to survive.

I lowered the richness of my organic mix and the SPG's leaves are still curling even though I've had to feed them to keep the leaves from turning too yellow and dropping off prematurely. In spite of this leaf curling I have still enjoyed bountiful, potent harvests from the SPG so don't dispair yet.
Nirrity
04-12-2008, 10:25 PM
Well, what is really forced me to ask this question is that I run totally 100% pure organic soil with 50% vermiculite. I balanced the soil pretty well and I have not faced any problem with Phnom Penh. Moreover, I didn't fertilize them at all throughout the whole cycle, and that works perfect, almost 1 gramm per watt with 250 watt HPS.
But it seems this Viper don't like it though it should be far easier to grow than Phnom Penh. Pretty confusing...
Lungus
04-12-2008, 10:57 PM
Yes I know the feeling. I am currently running four other strains in my organic mixes with no prob but the SPG and SSxC/K both get leaf curl even in a lighter mix. Both of them seem to flower well so I'm not going to sweat it too hard but I would like to get to the bottom of this leaf curl business. They show confusing symptoms. They got leaf curl as a sign of high N but as time went on they got hungry, yellowed out and I fed them some PB original, Earth Juice and Fish Ferts to green them up a bit. They are still packing on bud at a good rate though. Here's a look at the SPGs.

The left cola on the right picture in the middle (100_2711) looks alot like my Viper burmese pheno. I can only add that curled leaves are pretty dry... and mine have no yellowing... I suspect oversensitivity to heat and remove this plant as further as it possible in my box. Will see...
Lungus
04-13-2008, 09:01 PM
I am also wondering if they are too close to the light and it is too intense. The leaves on the clones don't curl, not until they are under the 1000 Watter for a couple of weeks and they grow closer to the bulb, which is in an air cooled hood so heat shouldn't be much of an issue as the Lungbox has been running between 74-80 deg. when the light is on, which makes me wonder if it's light intensity or something to do with the pH or amendments in the soil.
Nirrity
04-14-2008, 03:35 PM
...which makes me wonder if it's light intensity or something to do with the pH or amendments in the soil...
A lot wonders here :) I also think about intensity. I run 250HPS through cooltube, so plants can stay only 10-15 cm away from bulb without too much heat. But that doesn't explain why others plant of the same strain don't show such signs in the same conditions? Some genetic predisposition here?

go to full flush NOW! you have a reuptake problem caused by a SALT build up at the roots preventing the ferts from getting into the plant. the yellow is caused by the plant feeding on itself. just had the same problem and lost 1/2 my crop. run water thru each day untill it comes out the bottom clear. then use ph'ed 1/2 streaght nutrients until the last week - go full flush again.
use bigger pots next time and if you long veg then flush before flowering.
ph range is 5.3 - 5.8 for flower ph range is 5.8 - 6.3 for flower
full flush means soak the pot till it looks like mud, let dry 1 day and soak again.

No luci's here, thats a by gone era. Maybe his new self will help though. Looks almost done. Still seems like excess soil ammendments to me. Good luck and enjoy your nugs. Peace GS

They are 6 weeks in bloom only. Another 3-4 weeks suggested...
I'm curious what Blackseed pheno was used for this cross. C-ray mentioned some 'special' Blackseed pheno somewhere here, don't remeber where exactly:confused2::high:

Nice!
I run UV-B
Cool! :up:
Sorry, but I'm about to hit you with a ton of questions. I'm getting new equipment in a while and UV-b is on the list...I hate to bother you a bunch of Q's so if you feeel like answering any of them it's be great!
What model? What watt? what wavelenght(nm)? Is the light very directional? how many sq ft or sq yrd will it cover? How is the light penitration? How many "on" times a day, when and for how long? what have you noticed in terms health of cannabis? Do you only use it flower? What kind of light do you flower under, HPS?
Thanks!

I would check the Ph of your run off Nirrity.
You are showing classic Ph imbalance.
The "Rams horn" ie leaf blade curling under is K and P deficiency
The "Boating" ie The sides of the leaf blades curling up so it looks like a canoe is an Mo deficiency
Do a Ph check of the run off the next time you water
Great post canny!!! :D great info :D

Coverage is pretty low, as well as penetration, so I relocate lamp daily by hand. 3 hours a day, split into 6 30 min cycles... Start from second week in veg till last days... health is OK, curling in early days but then they assimilate and no signs further...

Thanks creator, quite sharp advice, but tooo late, another 2 week and they are done... to lazy to do anything now... I suspect bad soil... Something was changed in the one brand mix I used...

Cupping leafs. Plants are in 7 gal outside. 4 NL, 3 weeks old. During the day leafs "cup." Is that to much water? Plants look really healthy just leafs cupping.
