Looks like a strong sativa hybrid, let it go 11+ weeks. I had a lemon kush that didnt fully ripen until about 11.5 wks, and its about a 60%/40% S/I
Wait until those hairs all turn dark red, and then they will sort of get thin and curly...almost receding back into the calyx. That is when you cut...try to get at least a 20x Scope to check the trichs...you'll want about 30-50% amber. Heavy indicas usually attain that around 9-10 weeks, Sativas 11-12, depending on genetics.
You're almost at 9 weeks...another 2 or so would be good.
