Spotting/bleached spots on leavesOne of my plants has some light green spotting on the leaves but other than that seems perfectly healthy. I don't think I need to be worried about it but I'm curious if anyone knows what it might be? (just a mutation?) My camera isn't the greatest but it is visible in my picture.Week 4

I have a cool mist humidifier in my tent, using RO water. Two of my plants that are close to the humidifier have started to get leaves with rust colored spots and yellowing. The left two are fine. Any ideas? The only difference is the mist may have been spraying on the first two.Week 3
