Little Dead SPOTS on PLANT!! What is it?

got little dead spots on plant. the two leaves one facing north and the one facing south. Not the white tips. The dead spots on the actually whole leaves. They are like little speckles all over it. the leaves are also a little wavy. (DWC set up)

Don't really see this on the other plants in the same tub. Could this be from water droplets? I sprayed all the plants with water.





you can see it closely on the SOUTH leaf here:

go easy on the food how are the roots doing

don't know much about DWC.
However, using DWC you don't need to spray your plants. It will cause more harm than good.

looks like nutri burn when just starting use half strenth nutris.

it's only 1/4 of the nutes. very low strength. There is 6 other plants using the same nutrient dosage and strength but this is the ONLY one with this problem.
