Its only looks about out of pre flower. That's 15-21 days. Then you got a few a weeks of fattening, and then ripening. Most autos/fems flower, (that's as soon as you see pistils) you count and it should be done if its a fast auto 40days or a long one I've seen them needing all the way past 60days, Dutch autos take around 60+ days of flowering, FB you can get 40D. But for fems the norm is 56-63+ days.
By guessing you got 5 weeks left.
Good luck
