sulfur burner mishap

Four weeks into flowering and noticed a lil spot of pm. So I setup my burner on a timer to burn while the lights were out and something went wrong with the timer. It burned for a couple hours with the lights on. What should I expect? Is there any way to save whatever damage may have been caused?

Can anyone explain why its so bad to use sulfur burner during light period or what may happen if this is done?

Sulfur is highly reactive substance. The bulb itself will get coated with Sulfur compounds which isnt good for the bulb. You also dont want a spark with a very thick cloud of Sulfur, tho I doubt you could ever get it that thick. Also, the plant stomata will open during light hours and it the plant just inhaled a while lotta toxic stuff. I could imagine some of that S would incase within the plant and might have some longerterm issues. Mostly, I guess the plant just looks like a bad overfertilizer burn but I would imagine it lived.

Can you let us know what the results are?
