Ok, I took this clone about 2 weeks ago, the bottom leaves started curling under about 1 week ago.. I didn't think much about it because the top leaves seem to be reaching up still. In the last few days, as you can see, it started yellowing, almost like a nitrogen deficiency. It is in a solo cup in rock wool, and I keep it under a cfl light on top of my cable box. the temperatures of the cube do get up over 80 degrees and I have been keeping it humid as well as I keep the rockwool wet but there is no signs of roots coming out of the cube yet. should I keep going with this one or is it a lost cause??
