To me it looks like alot of the hairs are still white, and not even curled yet, the pictures are kind of a blur, but id say another week AT LEAST but id go until those white hairs change up a little bit and curl more, 1-2 weeks would be ideal maybe longer, have you checked the trichs out yet?
You got a couple weeks at least bro. Kinda hard to tell with those led lights on though. Snap some pics with some regular lighting so we can see the colors.
My thinking is like a month. Didn't you make note of when you flipped the light cycle to 12/12? I usually go 70 days from flip, but some I take at 60 days. Usually because i'm out and can't wait anymore. They really put on weight the last couple weaks.
