I have some Herijuana clones that I just transplanted. They were really looking good but in the past 5 days they are looking sickly. Leave seem to be wilting and the plants are turning yellow. I did give them some very weak nutes when I did the transplant and have been using superthrive in each watering. Last night I flushed them and am only using RO/DI water now. Can they be saved. I hope the picture is clear enough to see my problem.
