So just looking at your photos, @Newt is right. The Ambers on your sugar leaves are of no importance when it comes to determining if your girls are ready or not. Go through your top cola’s, and find a spot in between the sugar leaves so you can look in to the bud itself. I’m seeing some spots in your photos that show this and to me it’s got another week or so. Week if your looking for max thc and longer for more couch lock.
Looking up your strain I see the normal flower time is 8.5-10 weeks which means at least a couple days longer.
If it were me I would wait till next Friday and chop chop. Hope this helps and happy almost harvest time!
