Looks to me like normal aging of first leaves to me. The shoots look good and healthy.

Fan leaves will all die....especially the lower ones.

I follow the rules that say nute probs and other chemistry issues start at top.... and work their way down.

Those leaves just look like they are old and giving way to a lot of secondary spaces.
HARDDON Reviewed by HARDDON on . another problem... yellow leaves *pics* HELP!!! well my plant just recovered from a pH issue and now ive got another problem. my plant is about 5 weeks old, about 9-10 inches tall, is working on putting out its 11th node of new leaves. i thought it was in generally good health, but i noticed that the bottom most leaves were turning yellow. i thought nothing of it as i figured that they just werent taking in enough light to be valuable to the plant anymore.
