Some will argue this, as its widely debated, but I say you clear out some of the bottom 1\3 of your plants for better air movement in the bottom. Sure taking anything off the plant causing it to divert its attention that area for a day or two, but you look a tad crowded if you are at all concerned about mildew\mold.... it's better to do it early than late. just my 0.02

lookin good tho
