Hello there ogiro,
When the serrated edges of marijuana leaves curls or are tipped up, it's often a sign of temperature stress or problems with humidity levels. If this is happening to the plants which are closest to your grow light, that's a hint that the problem may be temperature related.
Good luck with your project, I wish you all the best! 👽

Usually heat stress or light stress (or both). I bet it's heat and your temps are running 85°F+ at your canopy. Or your lights are too close. Hope this fixes your problem.

Leaves Curling inwards early vegHello I’ve noticed that the leaves are starting to curl inwards. It has been very hot over the last couple of days with temps in the high 20s and RH any where between 45-60.
So not sure if this is heat stress or something else. Should this just rectify itself.
