Ive grown it before, and barneys farm recommends 9-10 wks. I think the lack of N is making her finish early though. Also its one of those strains where you CANNOT go by the hairs, it grows bracts with white styles and then a week later they are orange and a new set of bracts are on top of those with white styles, this usually just stops at about 8 weeks.
Im checking the trichs now.
