It’s at a decent point for thc. It’s not like your numbers are gonna plummet if you chop a week after peak thc, and likewise it’s not like you’re gonna have lost a ton chopping a week early from peak thc.. no one can look at pics and say this is the day it has peak thc. Not without lab testing.
This looks like it’s in a decent spot, but I’d personally let it go maybe a week more and chop.
I think dark periods do hardly anything.. but that’s up to you.
