This is a little write up that I originaly gathered from a few master growers from CW1.0
All credit has to go to Lucas and GrowGreen, and in NO WAY do I grow or condone others to grow,but if someone absolutely must grow for medical reasons and you want to grow hydro and you want the absolutely easiest and most fool proof way to grow and you demand nothing but the healthiest garden then by all means, you've just stumbled upon a pretty good read...
For this example we will run the PPM pen on a .7 convertion, and also be using a 70 gallon rez with growrocks. Also this is done with strickly RO water as are the add backs.

-Floranova Bloom
-Cal/Mag
-Floralicious Bloom

With a starting rez filled with RO water, add some Cal/Mag till you get 100PPM, then add about 10ml/gl of Floranova till your pen tells you 1340PPM. Blam thats it don't get much easier then that. Now your gonna want to run your rez at 1340PPM the entire flower period no flush required.
In order to keep up with the add backs Lucas/PH came up with a pretty simple add back formula that ppl live by. It goes a little something like this.
((target-current)/target)*10*70
-target=1340
-current=670
-gallons=70
-Floranova=10

((1340-670)/1340)x10x70 = (670/1340)x10x70

=0.5x10x70 = 350ml of Floranova Bloom to add back

got all that,it's really that simple. Keep in mind that if your growing with a E&F table with growrocks your gonna want to keep your PH at about 6.2 in the rez, as if you check your run off from the pots you will see that the PH in the root ball will be right around 5.8
If your going to be doing anykind of vegg time simply add about 5ml/g of Floranova Bloom instead of the 10, no need for any Floranova Grow as this formula has all the right N in the mix.
The only other thing that one might want to add to all this is on day 21, one could add about 5ml/g of some Floralicious Bloom to give your plants a little bust in aroma and tast.
Voila, here's a little contribution to this site CW2.0 and hope that we can pick up from where we left off.

hello TheForSaken,great info...
this may also help it is a program i got at cw
it`s called nutra solve it`s only 8.25mb and the
link only needs to be hit once every 30 day to
stay alive.theres a window you have to drop
in the righthand coner to download.i don`t know
who wrote it but it can be very usefull...it works with
any nute you input the data and it does the cals....

You got it Deltanugz, the Cal/Mag is to buffer the RO water,stabalize the PH. I know that Floranova makes a bottle for hard tap water(FN macro)? But my tap water runs at almost 300PPMs. I personaly like to start at zero and work up from there, I like to have control of what goes in the rez;)

nice post TFS, thanks

fwiw, cal mag is a bottanicare product, it works well with their other product, Pure Blend Pro, because it adds missing Mg, as well as raising the Ca and Nitrogen. Calcium acts as pH UP, whether its in tap water or in Cal mag.

Flora Nova works very well in RO water, with a dash of pH UP, your choice what kind of UP you use.. even tap water works, if its not over 200ppm. Most of the people and places I visit, have tap water above 400ppm, which imnsho, is not good to use, as it contains too much pH UP (Calcium)..

About addbacks.. it is a return to old school strategies.. Instead of dumping and replacing a reservoir, it has long been known that one can add nutes to a depleted res, and the TDS can be brought back up to original levels ~1300ppm

The groupthink against adding nutes to a res that is more than 2 weeks old, presents the fear that the plants are going to be living in their own waste products.. but in practice, many people go for a full crop cycle, without changing the res, so I have come to believe that the "waste products" model that applies to humans, does not apply to plants.

Very little of the nutes in a res is actually used by the plants. I now think of the nutes as a sort of electrolite solution, which allows for electrical conductivity and movement of ions within the plant. The actual food production for the plant comes from the atmospheric gasses, oxygen and Carbon Dioxide, which are converted to biomass by the plants response to Light.

to recap, Flora Nova works great, if the rest of the grow factors are met, oxygen delivery, co2 delivery, light delivery :-)

As one who started with res changeouts every 2 weeks and have learned even more I can say that Im aware of folks who have gone thru 3 full 12/12 cycles with only adding back to the res. After 3 cycles when changed there seemed to be more residue at the bottom of the res but yields stayed very consistent for each location.... hr
