Light schedule confusion


A question from a fellow grower:

my timer went off last night I mean it broke it never turned it off so I’m doing 12 hours of dark actually 13 I noticed at 4 o’clock this morning that my lights were still on so I turn them off 12 hours would be 4 o’clock this afternoon so I was wondering should I go right back in to,12 hours or 13 hours of dark because I’m in flower stage will this mess my plants up


The sooner you get back to your regular light schedule the merrier it takes several days for your plants to react to new light schedule.
