Sorry I seemed to have missed those pics lol it appears to me she is very close if not ready, the leaves have yellowed which means the plant is absorbing all the stored energy, sugars etc from the leaves, the pistils appear to be receding into the calyxes which is another good sign that harvesting is close/ready.
I think it's down to personal preference but I think you can harvest now, I've harvested earlier than this before and turned out just great! Good luck mate she looks a beauty!!
Happy Growing
