check the trichs dude. get a magnifying glass (highest magnification) or a small handheld microscope. look at the buds and see if the trichs are amber or cloudy or clear.

if trichs are clear do not even think about cutting it down. you get the most thc if you wait for the trichs to tell you when to kill the plant. you want to kill when the trichs are about 60-75% amber and the rest cloudy. trichs look like upside down falling watter drops still connected to the spout. so kind of like a nipple on the end of a hair.
