Hi @280bushkush! Buds tend to fatten up in the last weeks of flowering, and the moment you harvest will have a huge impact on your product's quality / taste / potency, so you don't wanna rush anything neither than proceed to harvest too late. You will need 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 (it lasts a few days), Amber trichomes mean the harvest window is ending, and THC is degrading. It's all about the effects you want. For energetic/uplifting high, you want the maximum THC so you must harvest when most of the trichomes are cloudy/milky, when the first amber ones appear. For medicinal properties and/or couch-locking effect, you want more CBD/CBN so you must wait for 20-30% of amber trichomes. Don't forget to flush your medium with plain pH'd water, 7 to 10 days before harvest, this will ensure you a clean product without any nutrient/chemical left in the buds. Harvest in the morning (before the light turns on) if you want terpenes to be at their peak. From what I see on your latest pictures, I think you still have 2 to 3 weeks to go. Hope this will help, keep us up-to-date and enjoy your harvest 👊
