If I were you, I'd plan on chopping in a week.. no more... what you DON'T want to have happen is for the THC to degrade and be left with something that is no good... I'd rather, actually, see a picture of the whole plant alongside these photos to get an overall sense of what's going on and if she's ready... has the plant started to fade? Are the pistils about 80% brown? If so, chop!
Good luck!
