Okay so heres an interesting defect that im not too happy about, a couple of the lower leaves on 2 of the plants are looking nasty. The bugs are gone all but some little flies that like to hover around.

I wanna know what it is that is causing the leaves to decay like they are, and if i should just chop the branch etc.

Other than those 2, the other 7 are loving the hell out of their new homes, got about 2 inches in the last couple days.
