start trimming all the smaller stuff under the screen that is not getting any light. This is good for a number of reasons. It concentrates more energy on the big colas and having less foliage under the screen with prevent disease. I have done scrogs defoliating and ONE not defoliating. My non defoliated scrog was the only one I ever had problems and got Powdery Mildew very bad. never again. U might just end up with larffy crap under there.. so my advice.. clean it out good where the light don't hit.
Looks awesome, nice work!
