I do belive drying improper can decrease thc in the buds, but by the looks of things your doing the right thing. ive only seen once harvest...and it was basically similar to yours and the buds came out great.

your buds look good, but the best test is always to break that bud up, roll it up and smoke it, then let us know! good work. how many plants? how much did you end up harvesting? what kinda light setup?
