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.
