Trichomes ripe?

A cursory review of pictures leaves me with the impression that your flowers are ripe. I typically harvest to maximize cloudy trichomes and my trichome maturity looks similar to your flowers at harvest. You can also see some of the sugar leaf cannibalizing itself from the tips in, which presuming you had no nutrient issues up to this point would indicate waning levels in the soil or solution (such as if you were flushing or ceased an amendment program). With the condition of the foliage, I wouldn't expect much more to happen other than ripening and possibly terpene production.
