to much light...

My plants have been flowering for 2wks, lights on 12/12, but today one of the timers broke and one of the lights stayed on for an extra 4hrs.. Wat shall i do,
all advice appreciated..

Nothing u can do its done. Just don't let it happen again or too often or ull end up with either hermies or a dissappointing yield or both

Just get them back onto their regular light cycle. As already said, try and not let it happen again! Good luck.
