DWCHCanswered grow question 5 years ago Pistils indicate flower maturity, not trichome maturity, a good lens, at least 8x or 10x and watch those trichs. I go for 20% Amber personally, but I also favor indicas, sativas I go for more 35%. I like the heavier, yet still heady buzz.. THC peaks at cloudiness, and slowly begins converting to other compounds when the caps flatten or shrivel, and they turn Amber... After this point the only gains are mass, the buds continue to fatten, but potency will decline relatively.. so if potency is your goal over yields, then max cloudy on the side of Amber is what to watch for.. and over the whole plant, don't forget to check the mid and lower buds too and take an estimated average.. lower finish a bit later... Cheers! Keep it Green!
