New to the indoor grow. How much longer do you guys think on these? Pics inside

I got these as clones from a buddy of mine. He told me that they are the Headband strain. I have been growing them under a 150HPS. They have been flowering for about 5 weeks now. I am happy with the look and smell of them, but not sure how much longer I should wait before harvesting. Pics below. Any help is appreciated. I am seeing about 50% of the hairs turning orange/brown already.

prob a good 3 or 4 weeks

At least 4 weeks.

Every seed site says 9-10 weeks flower time.

Thanks guys. It has been flowering for at least 5 weeks now, so a little longer isn't going to hurt.
