Get the trichome microscope out and check trichomes.. pistils have nithing to do with rippening. Certain strain will have lots if white hair left at harvest sone strain will have hair falling off and that is just genetic. I can have have all hairs turn black in less then 24h 4 weeks into flowering . Hairs can help figurout the harvest window but all strains are unique.
