Is the curl up natural?

A customer has a question and I hope we can get some opinions on it, thanks

Just a quick question about my leaves.
Is the curl up natural?
Am I spritzing to ofter? I only use water on the leaves but do it more than twice a day.
Other than that the WW auto’s look very healthy.
Any input would be appreciated.

Could be heat stress which is remedied by venting and air circulation but need more info to be sure


@Fever correct! @ILGM.Becky It can also be from nutrient stress (not burn) like a hot soil. Maybe raise the lights a little and don’t spritz/mist during “lamp on” hours. Spritz 5 minutes before lights out.
