Timer didnt go off last night just got up and light was still on need help!!!

im in the 7th week of flowering and for some reason my timer didnt turn off the 8am like it should it is now 11 so my plants got 3 extra hours of light is that bad? should i change like 12/12 to turn off and on at 11 now and no 8? please help

no keep ur same schedule. if this is the only time its happened you should be ok. just dont make a habit of it.

yea this is the only time its happened my timer was on the on mode and not auto mode for some reason so it got some extra hours of light thanks for the advice
