Last week of flowerin, all pistills brown but trichomes mostly clear

Im in 8th week of bloom. Almost all pistills have turned brown. And leafs have started to turn yellow, and die. But trichomes seem to be 50/50 clear/white.

Should i still harvest? Is there any problems to let it continue even though pistils are brown and leafs are dying?

Thanksfull for any ideas

pics would help us help you

i would harvest according to the feeling you want, clear trichs aren't degraded enough (this degradation causes the high feeling), cloudy trichs are more of a heady high and amber are the most degraded trichs which give you more of the couchlock type buzz

could be genetic or breeders BS flash dry a taster bud
