Plant stress after loss of power

The other day we had a warm rainy day that caused the power to go out for about 5 hours. luckily I hadn’t yet watered my plants but even still I was struggling to keep everything under 70%. I’m growing autos and about half way through flower at the moment so I know they wont like the stress but now a lot of the leaves have curled upwards mostly just the tips but I’m just curious what kind of damage it might have caused or what I should be looking out for at this point.

I wouldn’t stress. It should be fine. Especially since it is an auto
