I bought 6 clones from the bank and put them in my rainforest aeroponics system and they are about 4 weeks old and i kept a flourest on them and after a day or two the leaves startd curling and discloring and the stems are still green but i have now clue whats wrong, itas my first time growing and im using the three part flora series, which im puting in 2.5ml/gm, and im using a 400w hps now, i was wonderring if there is anything i can do to save them
