If this were my plant I would be ready for harvest. The more i row the more I realize for me personal, id rather my plants be slightly under ripe, than over ripe. Some people run their plants two weeks longer to get fade and all the cool colors, but I'm already exhausted too much as it is so i need sativa effects most of the time. Running longer than needed is also a way to invite the plant to mold so its a bit of a fine line. my last run. I was worried because one of my plants i harvest at 8 weeks had more than 50 percent white hairs. after drying and curing. its my favorite smoke out of the bunch, so theirs that. Flushing is a waste of time and water, and nutrients imo.
