I ruled out pests. There are no pests. I ran some ro water through one on of them and the ppm is at 1400. The ph is at 6.8 (they are grown in soil). I have all the handbooks and such and I am still unclear what it could be. Its only effecting the leaves around the bud site. The only thing that that looks somewhat like this is boron def. I was under the impression that boron def is rare. I'm going to flush tonight and treat with eyewash(boron) and see if it helps.
