Purple Urkle Clones

Still plugging along. I have to admit...I'm a little disappointed with how these buds are developing. I expected them to fill in a lot more I guess. For all practical purposes, it looks like these will be ready for harvest soon and the buds are about as big as they're going to get. I'm sure some of my problems are from poor lighting and that's because these plants have grown so tall they are almost in the light fixture. If you bend the close branches away, they are no longer in direct light. Trying to keep moving plants around to keep them more uniformly illuminated. Not seeing any gnats buzzing around anymore -- maybe I got them all. The PM still seems to be a mild problem. Every day, I'm finding this crap on a few leaves here and there. I took some pictures with the microscope and can see the trichomes. They are well developed and starting to get milky. I'm guessing this puts my optimal harvest about 1-2 weeks away?
