It depends on how you like your high.
If it were my plant I'd pull it right now because I like my high to be more of an upbeat than a couch lock, and you're in the prime of that stage right now. If you want more of a couch lock high then give it a couple more weeks till you're satisfied with the trichomes.
Either way, I'd suggest pulling a branch or two and start to dry them so later if you harvest with more amber triches you can compare the high and figure out what works best for you.
Good luck!
