Harvesting is ultimately up to the grower. Itās hard to answer when we canāt see your grow. With that said, if you think itās 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 ābe a plantā. 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. Iām sure thereās more educated growers here that will answer but harvesting is all on the cultivars. Good luck
