You can chop after 1 week of flush even if 10 days is better. I feel like you'r in the good harvest widow to chop now or in 3/4 days

Nice pics! I think you've answered your own question. As the trichs mature they will begin to move from clear to cloudy and then finally to amber. If you're shooting for less couch lock and more "raciness" then you ideally want to harvest prior to the trichs turning over to amber. If you've already got a little amber and the plants leaves have been fading (that yellowing you're seeing when the plants consumes its nitro stores) then you should chop now. 6 days of flush is less than most prefer but realistically - it's also a point of contention amongst many as to whether or not flushing is even necessary. You're good to go - grab the scissors and get that girl to the rack👍
