would it be ok to switch from 18hrs of light back to 24hrs? i've had the seedlings for 3 days about in 18hrs of light and been thinking would it be ok to switch back to 24hrs without stressing them?

why would you want to go to 24hours?

Plants get rid of built up toxins during dark periods.

I personally propagate and veg under 18/6 as i firmly believe that the plants need some down time to help them remove toxins and develop root mass.

You could quite happily switch and it will not cause them a great deal of stress but i wouldnt run 24hours personally.

then leave it on 24 for a few days if you dont want to get up early and just switch it back to 18 when you have your timer.
