Maturity of the herb has nothing to do with how many pistils have turned orange, though. It is a must to look at the trichomes under some sort of scope. The only reason I said a week or two, is because from picture 1 (best perspective in my opinion) you can see the trichs on one of the bud leaves are nice and amber, but many other ones are clearish/cloudy. It is really hard, if not impossible, to tell the maturity of a plant without really good trich shots. That's why I invested in a veho 400x microscope....Never have to guess
