I ran Polar Lights 2 a few months ago and mine did amber up. I was at about 20% amber when I harvested. From the looks of picture #5 you have just a few amber towards the top of one of your calyxes but I don't see much more. Let her go another week and look at her again. Harvest according to the high you want, clear trichs=THC not quite developed, cloudy trichs=head stone, amber trichs=body stone. The more amber the more degraded the THC.
