Weird spots on some leaves

This clones were revegged and have finally started growing normally. a few days ago I noticed these spots or marks on some leaves in one of the plants. Does anyone know what it is?

More than likely you Nothing to be concerned about, young plants do that sometimes. It’ll grow out of it. Just monitor, but I wouldn’t worry unless it spreads or gets much worse.

I can see from the one leaf in pic 2 that you are pulling mag, I’d turn your light down a bit.
