Purplish newer growth at top of, and scattered throughout several colas. I'm concerned they could be pollen sacks, so I'm trying to figure out whether its hermied, or just swelling buds. I plucked a few off and opened them up - didn't find any obvious pollen inside, just hollow sacks that may very well be normal calyxes. Not sure. Trying to determine whether to keep on going, or if I should cut my losses and harvest asap?
