Lookin' great over there! You asked me if I thought you were using enough N, and without knowing what your feeding, I can still say yea, it looks like your right in there. I may have over done mine just a tad in my original mix, and alot of mine are going to be pretty much green right uo to harvest. Not really a big deal if it's all organic, and there's no EXCESS built up in there not being used. I pulled a couple buds the other day, and just let em' dry quick, in like 3-4 days just to see, and it's burning clean grey ash already, so they're going to be good with 2 weeks of strait water now! Your stuff is looking very good IMO.
The RIU Smoke -out is a cool idea, one of you production wizards put it together!
