On week 10 of Autoflow, stop feeding about a week ...

From what I can see, you're in that window where things are really more of a preference. From what I can see your trichomes look mostly cloudy with some clear mixed in. I would call that the beginning of your window. Some would rather chop once they start to see more of a mix of amber ones in there and some strains will push a late fattening during this time. You might have been able to feed a little longer but if you think you are going to chop soon you can just push water and let it leach what it can from the soil and fan leaves. You don't have yellowing leaves so you got room to let it go a bit longer if you want.

Too late now to expect anything more, she is well and truly ready for harvest and will not grow anymore. Only real way to grow denser buds is to invest big in your lighting. Leaving the plant in extended dark will just stress/confuse your plant and is unnecessary. I have concluded after 35+ years of growing, is to leave your plants as normal as possible (stress free) before harvest and harvesting about an hour after the lights come on as the best time for prime terpene/aroma quality. Hope this helps,.......... Organoman.
