I lost my first plant to unknown cause and now my second plant looks like it is doing the same thing. I am running 400W MH 16/8, res temp around 70, air temp between 81 (lights on) and 65 (lights off), PH 5.8-6.1, i dont know my PPM and i am using a 3 Gal bucket with 3" nets pots and hydroton medium and one 6" air stone. My plant got to about 1 in tall with two true leaves at about 8 days in then i added 1/4 nutes. The roots where just poking out of the bottom of the rockwool at this point. I was top feeding the plants with the same concentration of water that was in the bucket. The next day the plant leaves started to sag and now on day 11 the leaves are curled up. I flushed my bucketed yeterday night and just added regular water PHed to 5.8 but still not change in plant. I assume this plant is a lost cause at this point but i want to know what i did wrong for when i start my next grow. BTW i am running GH nutes. Any help would be appreciated.
