no one can help you without some proper images, turn off lights and use camera flash

I agree, use your flash when the grow lights are on.
or pull a damaged leaf off, and take a picture.
From what I can see It might be a Magnesium issue.
I'm not 100% sure with out better pictures.

Good Luck on Your Grow.
