Help!! I screwed up my timer!!

Hey all, not sure where to post this: yesterday I decided to switch my timer to 14dark/10light. I usually have my dad do it, but decided I could do it myself. I messed up royally and my timer stayed on for almost 23 hours DURING FLOWERING! My plants only have 2 more weeks to go, if that, before harvest. I've already harvested 2 and was turning the lights down to speed up the process.

Does anyone have any advice, similar stories? I'm scared my plants are going to die or go back to veg, or something!! I'm a first time grower.

um it helps to tell what you did wrong

I thought I did: I had my plants on 12 12, then changed the timer to 14 10 - at least i thought- but it stayed on for 22 hours. They're in week 6 of flowering. Will this hurt them?
