Get some neem oil mix as directed and add about 1/4 teaspoon of dish liquid per gallon, to keep the oil from running off the leaves, asap and spray the bottoms, tops, and every crevice of your plants, and surrounding area, until they are completely drenched. I'd do this a couple hours before the lights come on so it has time to soak in and dry and not burn your leaves. It also looks like your plants are heat stressed quite a bit too with all of the margin roll going on.
