In my opinion that lady has a little time to go, enwhysea. Everyone has their own theories on when to chop, x% clear this, x%amber, stigmas so and so %.....but short of counting every hair and trichome on your grow, well that's all I'll say about %. For me, a plant is ready when the calyxes have completely swollen and they are growing such that the hairs start to recede, much like men in old age.
The problem with trichome %'s in my eyes is that all plants trichomes mature differently, some strains you can grow for ever and you are still seeing no amber, others seem to squirt amber out in the cure, plants can also get amber trichomes from damage as well, so all in all, I go for how it looks. I would say you got 2-3weeks. It's hard when you want to chop to try and not keep your hands of it.
