deficiency? help pls

[leesus]

I'm growing in peat moss/perlite. Using advanced nutrients ph perfect micro grow bloom and distilled water. I called and asked if I needed cal mag and they told me I didn't need it using distilled water and their nutrients. I'm guessing it has cal/mag in it? Anyways these spots appeared over night. I'm a first time grower so I have no idea what it is. I don't see any bugs. A gnat might have flown in but the other younger seedling doesn't have this problem. Yet anyways. I had let it get kinda dry but not bad. The normal check with the finger and still a bit moist a little deeper down so I watered. It felt light. Any help is appreciated

High hopes we figure it out. It might be some type of fungus or something
