Hey buddy, it all depends on the high you want 😊 the more amber trichomes there are, the more narcotic the effect will be, and the taste changes too.
Trichrome checks need to be on buds, im THINKING they COULD be leaves in picture, WHICH tend to MATURE at a different rate.
So yes if the buds look like that it's ready.
I should know, I have nearly grown 5 plants badly so far in my life
