No, not if you've got decent buds growing. I would double check to make absolutely certain of the following:
Timer operating properly
No lights like LEDs have become exposed
Meters are operating properly
Then, I'd start inspecting closely. If it's just a few nanners they shouldn't impact overall bud production. The second issue of course is seeding, but that's fairly easily prevented by spritzing with water after plucking out what nanners you can find.
If they start popping true male flowers, then in my limited experience with that kind of full-on hermaphroditism, the female flowers stop growing/building, and in
that case, your best course of action is to toss and start again. Otherwise I say keep them going, pluck & spritz.
