Hi
@Bertabud! Pistils can be a clue, if you noticed that new pistils have stopped appearing and old pistils have almost all turned red/brown 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/Thin 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 (less THC, more CBD/CBN). Looking at your last pictures, I think you're 3 to 4 weeks away from harvest, those buds can still fatten up and produce more resin. I'd recommend keep on feeding for 10-15 days then proceed to flush for 10-15 days (with plain pH'd water), depending on the trichome's evolution. As long as most of the trichomes have turned from clear and thin to fat and milky you know the 'harvest window' is open, even if you don't see any amber. Harvesting too soon (too many clear trichs) will result in a uplifting/energetic effect but you will lose some terpenes & oil potential. Waiting longer (too many amber trichs) will result in a heavy stone/couchlocking effect. Check out some other diaries of this strain on GD, most of the growers had to push her betweek 9 and 12 weeks. Hope this will help, keep us up-to-date and happy growing 👊
