Probably irrigation residues?
Observe the evolution of these spots carefully every day and check the sheet from behind. Have preventives like diatomaceous earth or potassium soap on hand.
Regards!

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...

Nute burn or gnats?Is this nutrient burn or fungus gnats? I started to see signs of my leaves starting to lighten. So I moved the light away and it didn’t solve it. So I started flushing, which seemed to help at first but because the soil is always wet I’ve got lots of fungus gnats flying around.

Bright green spots and wilting.I seem to have some wilting with some bright green spots on some leaves. I just potted up and she's at 20DLI, 0.6 VPD, 790EC @ 6.0pH. 75F, 71%RH, autoflower in canna coco pro plus.I turned my fans down a little since they were a little aggressive, so I'm hoping that's the issue.
