I'm with darkdestruction on this, got a good few weeks left in her, she looks like she is still putting out new stigma's. When the stigmas start to reced the calyxes swell up and they grow over the hairs. This is when to harvest imo, I think a lot of people see an Amber trichome and think they got to pull there plant down, the last week or so is when the plant puts serious weight on. I had it with my outdoor this year, checking it seeing Amber, and another more experienced outdoor grower said, don't worry, it's normal, they get a bit more damaged and as such the damaged trichs go amber coloured. Not being an auto grower myself I wouldnt say 100% but I am sure it's basically the same with autos as far as finishing the plant off. Good luck, be patient and you will be rewarded with an extra 25%.
Peace, DST
