If i zoon in on this plant, i see everything is milky, but it still has some white hairs around, not everythingg is turning orange. This has been on flush for 8 days. Outdoor red gorilla girl autoflower on aprox 85 days
not every stigma turns brown at peak thc harvest. basically there are 2 main harvest windows, one for thc content and one for yield. all pistils brown is for yield and majority of the trichs milky is for cannabinoid content. usually if you wait for all stigmas to turn brown so will the trichs which indicates degradation of cannabinoids.
Milky is when your thc content is the highest. Usually milky and a little amber is ideal. So if you are all milky you might have a few days to a week left or so.
