nanners aren't too worrisome, but if it popped entire pollen sacs, your whole tent is likely seeded if they opened up.
always a matter of context whether you remove it or not. Could always make bubble hash if it's heavily seeded. it will have a reduced yield with fewer trichomes, but better than seeded weed. also, how much time you've already invested and how many plants in the tent might influence that decision too.
if pistils were already mostly rust-colored, that means they are not receptive to pollen. Or, it's a sign they were previously pollinated. The pistils turning color early would be a bad sign. they die after pollination.
