Purple Urkle Clones

Buds developing. Looking good. I think stretching is done. Did more trimming and used green cleaner on remaining leaves to get rid of powdery mildew. It appears to be working. Only a few leaves this morning with slight evidence of PM. I will keep up the spraying. Gnats are still around. Even though top layer of soil is really drying out between watering, the little bugs are still showing up on my yellow sticky cards. Waiting for diatomaceous earth to show up so I can be rid of them once and for all. Still concerned about my trimming and not knowing what I'm doing but so far, plants seem happy. My biggest problem I feel, is that both plants have grown within millimeters of the grow light. The light is all the way to top and I have resorted to bending (LST style) one of the main branches to keep it below light level.
