Do you find you can keep the light panel closer to the plants without burning them?
I don't know how close these lights can be to the plants but the manufacturer recommendations begin at 36". So far I learned when I moved a 1000w panel to 26" above the plants, all the burning, bleaching and discoloring stopped. Now I'll have to move these plants to another area with a 1200w LED on a mover. At this time I have only 18" of altitude above the plants.
