What's the spots from

Having spots appear on the leaves, haven’t a clue whats happening, I raised the light to 22inches above canopy… maybe was thinking it was a cal mag issue, but one leaf has something on it…

Need help please, this plant is at 5 weeks

Closing thread as we are addressing it in another. Try to keep similar (or same) posts to a minimum and preferably in one centralized location
