On my 6th grow now so im far from an expert. I would guess 10-14 days remaining, but idk your lights or feed schedule. Besides the trichomes, I like to wait for almost all the hairs to change from white to orange. If About 95% are orange you know your girl is tapped/tapping out. Ive also learned that if you water and feed PROPERLY throughout the grow, you can avoid the flushes. That means exact amounts of nutes (which varies per plant, per grow) and water til runoff every time. Ive only fed and watered properly thru a whole grow once. If youve been juicing them heavy with fertilizers i would recommend a flush min. 6 days, max 10 days before harvest. My first grow turned out beautiful and i over fed and overwatered constantly. But i didnt flush. Cured, It had absolutely no weed smell, just a chemical-lawn mower type smell so i never smoked it. I attribute that smell to not flushing, but maybe im wrong. One thing that is always true is what works for me might not work for you. Do an experiment. Flush half the plants, dont flush the others and see if you notice a difference. I also leave mine in the dark for 3-4 days before trimming. It allows the chlorophyll to deteriorate im told. I am positive that the darkness makes them much more tasty and smooth, ive done the pepsi challenge on multiple strains and the ones in the dark have a unanimous decision every time, but its hard for some people to wait that extra 4 days to trim.
