Just my perspective. I go by both look and scope. It does not in my opinion look done. I've had plants with a projected 55-60 day flower, even at 90 days they weren't complete. I know this because I had two area with the same exact cloned plants, I had to take down one section at around 68 days, those plants looked immature (like this plant), damn right they got me high as fuck, and smell was mediocre.
The others i just took down a week ago had much more density, the catylcs were swollen and hairs were brown. I can not yet judge the smell or the taste because the cure isn't done, but the high is much more out of this world.
Like I said its my opinion.
