Light cycle disrupted for 5 days

I have plants that are 60 days into budding and some that are 30 days in and I added a new light and timer and the timer reset somehow so the one light out of three has been on 18/6 for five days. Is this bad? I don’t notice anything bad happening to the plants just seemed like they stayed the same size and didn’t grow no more for this week but that’s about all I noticed. Any help appreciated thanks

They’ll be fine, just get them back to 12/12.
