curled leaves?

[vaping]

i have two plants out of 14 that curled when i put them from 24 hr to 12. all others look lively. can it be stress? it was stormy for a few days and had no direct sunlite for 3 days.

Did they curl from the outside in or more of a spiral curl ? A pic would be helpful if you can bud.
