Hi
@AnneW! Pistils can be a clue, if you noticed that new pistils have stopped appearing and old pistils have almost all turned red and curly, but the best way to ensure it's the right time is to look at the trichomes with a magnifier/microscope. Clear/Transparent/Skinny trichomes mean it's too soon, Milky/Cloudy/Fat trichomes mean the harvest window is open, Amber trichomes mean the harvest window is ending, and THC is degrading, turning into CBD/CBN. Looking at your last pictures, I think it's a bit early, because I see loads of white pistils so that makes me think your buds are not fully mature, but no one can tell better than you (with the help of a magnifier/microscope). I'd recommend to keep an eye on trichome's evolution and start to flush when you see the first milky trichomes, for a balanced high you probably want 25% amber 75% milky. Hope this will helpo, keep us up-to-date and happy growing! 👊
