Harvesting is ultimately up to the grower. It’s hard to answer when we can’t see your grow. With that said, if you think it’s time to harvest, it probably can go another week, or two. One mistake I made early on (a lot)was not giving the plant enough time to “be a plant”. Do you have a strong magnifying glass or jewelers loupe to examine her trichomes?
Is she an auto or photoperiod? Have you done any research online to see what others have done? Research the plants history to have an even more accurate idea. I’m sure there’s more educated growers here that will answer but harvesting is all on the cultivars. Good luck
