Leaves Curling problem

i'd stop misting them. Claw can be nutrient related, but could also be a little less perky while acclimating to 12-12, especially if lights are ~50% more intense. stick to a good wet-dry cycle of irrigation and if it claws more, dial back dosage when you do fertilize. stick to routine and adjust dose.. simple as that. I'm assuming at this point you have ramped up to some 'max' dose. make sure entirity of pot is saturated with no dry pockets. this requires some runoff. I'd get a little extra runoff when fertilizing unless some sort of living soil or super soil. This just helps maintain proper concentrations throughout substrate. Wait for top 1" to dry.. get familar with weight of pot. a simple tug can tell you when it is time. Allow that wet-dry cycle to happen. As long as problems are small, can always wait to adjust next upcoming cycle. whether you do every-other fertilization or every third .. keep doing what you were doing. Makes adjustment easier to move 1 dial at a time.
