Anyone know what these discoloration spots are?

Hey y’all. This is my first grow with autos. Everything else is in super soil and looking great but the one I have in normal potting soil that so far I gave fixing liquid big bloom and grow big. Also gave it some cal mag a couple days ago

Any help would be much appreciated


It’s normal leaf variegation and nothing to worry about. It’s common among young plants.


always cool to see
