lights got turned on 3-4h late should i be worried?

Like the title says, should I be worried? This is my first major mess up but a few times before the lights would be turned off or on like an hour or less later then they were suppose to. I was under the understanding that more dark time on accident isn't too bad. So basically today instead of 12/12 they got 8/16 should I be worried or nah? They are starting there 6 week flower

12 hours or less of daylight will be fine, you just want to shut them off/turn them on around the same times, the plant has an internal clock, and if you mess up a lot it will screw with the plant

what i'm trying to say is try to keep it on the same 12/12 cycle ex: 5am to 5 pm or in your case 8 am to 5 pm then fix it the next day to 5am to 5pm

You are going to be fine. Don't change anything at all.

no, you should not be worried.

If they did turn Hermie I here anything that can be done to not chop the plants down? I can't afford to and am in week 6 n a half of bloom so there's recall not to long left so is it even that big of a deal if they did? I just don't want meds chalk full of seeds but one or 2 Herr n there doesn't bug me as long as its quality

plants, cannabis, flower depending on the hours of darkness, not the hours of light.. so long as they got their 12 plus hours of darkness they're fine.. if you had left the lights on it'd be a much worse mistake, but even doing that won't hurt anything once imvho..
