I asked you this in your budrot thread, and you didn't answer me, so I'll ask again.....did all the pistils turn during the same week, or was it a slow gradual process? I had suspected pollination, before you mentioned a lack of trichs, or odor, and now I suspect it even more. I lost two back-to-back harvests this year, due to a hermie that I never did locate, and your pics look the same as mine did,...all the pistils have turned, the calyxs aren't swollen and juicy, and the buds look generally 'airy'. I've only grown one sativa strain, but, it was always sprouting new pistils, even when it was mature, which is more evidence. Cut off a few of those calyxs and carefully cut them open. If you see a tiny light-green ball developing inside most of them, you've been pollinated, and have a hermie hiding somewhere. I hope not, for your sake, but the evidence is pointing that direction.
