Ok, I am all caught up. First off, thanks for the portable scrog tutorial! I do a lot of moving of my outdoor plants and now that I've got some photo clones growing through next fall I can probably use that idea for supporting 9 months of growth!
Two DE suggestions. First one is mix 4 tbs DE to 1 gallon of water, mix, and spray your leaves' tops and bottoms. Dusting only takes care of the tops and the way DE works requires the bugs to walk through it. Most of our bugs live on the underside of the leaves and miss the top dusting. Also it eliminates the inhalation problem.
Second thing is I have read not to use DE in flower (I don't think you have but for those following along). The DE gets caught up in the buds and you end up inhaling it when smoking. Inhaling DE is bad for the lungs!
Carry on with what you were doing, and doing it well
