Almost my favorite plant and ready to harvest!
Just 2 days in darkness with a low temperature to finish and then I'll cut her down.
The others need a week more to grow but they're really not as purple and frosty as that one.
You are right in the window
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.
