from the pistils, looks like their done (i like around 80% of them to be withered)
but see if you can get a scope so you can check the triches cuz thats always more accurate
give it another week and post pics again. It's not the hair color, almost all should be red when they're done. You need to check the trichs to see if they're where you want them.
so you want to chop at half cloudy half amber? its cool if you do i guess but the thing is if you wait till they are really done your gonna get denser and bigger nugs since the last few weeks before its totally done are when your buds add most of their mass. I'd say at least 2 weeks till you reach 1/2 and 1/2 still but i cant check your trichs and see them personally and have never grown that strain so it's a bit hard to say for sure.
