I don't know why the genetics would be different in a leaf. If it roots and gets neuts it should grow. But you should try cutting off about 60% of the leaf area. That way the energy will go to maintaining root growth, not tending to leaf health. Let the neuts come from the medium not the leaf. Anyway, that's the experiment I'm trying today. I have a variety from defoliation. I topped a couple nodes beneath a failed FIM, yes I missed the miss, and that's my healthiest clone so far. Just going for the tops won't build much of a clone army so I'm working other ideas. BTW I'm new and just trying to figure it out too.
