i'm not a regular fixture here, so take this advice as it comes. The trichs will turn according to the maturity of the plant, but in my experience with safron is that they turn fast, and they continue during the curing process. GO with your dates and just check regularly, i try not to cut early although sometimes, once or twice, to many of the hairs just get too red for my liking and down they come. (I figured i forgot the maturity date)I've also found a different feel and taste of the final product when cropped too early or too late. To late makes me sleepy, to early makes me wonder why i didn't have more patience.
