hermie fucked up other plants

Nothing you can do........just let it runs its course and harvest as normal. You might have to pick out seeds when consuming, but no biggie. Seeds from hermie pollen tend to be hermies too, they will not be "feminized" and are useless for future grows.

I would finish the grow because the damage is already done. The seeds might not be horrible and you can pick it out when you grind. If it’s really bad you can always make hash. I would not keep the seeds, more often times than not the seeds produced by a non stressed hermie plant also have a greater chance to hermie as well. Hope this helps.

Let them finish and get some smoke. It might not be as bad as you are thinking.

If there are seeds, the pollen has already done its job. This lowers the quality of your buds but doesn't mean they're not usable. You can harvest and remove the seeds if there aren't too many.
