From my experience it would be sunburn or water spots. Im not sure.
Though I would recommend removing the tinfoil plate they are on, it causes unwanted heat spots and creates un-even distribution of lights to the plants. Same reason you never want to use tin foil as a reflector in your grow room.

Yikes. Looks Like it could be pests. Usually white in leaves means iron deficiency but those distinct spots shout pest at me. Good luck.

Looks like pests on the middle leaves and a nitrogen or sulfur def on the bottom ones.
Nitrogen (N) - Restricted growth of tops and roots and especially lateral shoots. Plants become spindly with general chlorosis of entire plant to a light green and then a yellowing of older leaves which proceeds toward younger leaves. Older leaves defoliate early.
Sulfur (S) - Resembles nitrogen deficiency in that older leaves become yellowish green and the stems become thin, hard, and woody. Some plants show colorful orange and red tints rather than yellowing. The stems, although hard and woody, increase in length but not in diameter.
