hmm..okay, the plant looks like it was healthy until it wilted. We don't know how much roots were sticking out of the bottom of the cube when transplanted however. The obvious signs are dryness, and we know this is rootrelated. So we must do whatever we can to manipulate the enviroment so its easier on the roots and plant. I don't think the plant is actively growing if it is wilting as the stomata would be closed, so we don't need to have it in direct light for the time being.Indirect light or weaklight is fine as long as the timing schedule is maintained. Darkness for recovery sure would not hurt if you are running yours lights all the time. We are trying to negate heat and stress. Covering or misting the clones may help relive some moisture loss. Really, if the roots are dry, we need to wet them. So go ahead and top water the cubes as thats where the roots are. I know that you are wanting to have the roots draw out after the bubbled water, but roots will not grow till the plants recover, and the water must be bubbled furously enough to make it up to the roots at the cube bottom. Perhaps you could raise your water level to the bottom of most of the roots till the plants recover, then let it drop slowly, drawing the roots out as it does. I suspect just bubbling at the bottom of the pots is not forcing the water up the roots enough. Also one needs to bubble fairly 'furiously' for this method. Cooler waters will also help ease stress, sometimes its amazing how dwc can heat up under the hid lights. The transition the roots have to make in going from a wet media like rockwool to a dry media like lecca is never an easy one for the roots to make. Hope the girls recover. What have you put in your dwc water for nutes and the ec?
