Yellow spots? Help!

Hey everyone, my plants are around 35 days old from germination. I just started noticing a few leaves had some yellowish spots on them. I removed the affected leaves, and I'm posting pictures of them. Any help with diagnosing this problem would be great, thanks.

Good call, I'd say so too Chris. What about the underside of the leaves as well......

What would you like to know? I got 2 gorilla glue and 2 blueberry, and they all have touches of it. Nute splash could definitely be the issue, it's what I was thinking. I'm just worried it could be some sort of fungus. I'm including a picture of what the full plants look like.

Humidity is kept between 40-60%, temperature is around 70, growing in coco coir using Canna Coco nutrients. Ventilation is good. I also have a fan running on them constantly. My lights were a little bit low for vegetation so I raised them higher last night, just in case the lights could be contributing to burn.
 
Lights are 320W LED, pH of solution is 5.7, EC is 1.6. Nutes are all Canna stuff, so the Coco A+B, Cannazym, and Rhizozym. I just follow their feeding schedule. I'm doing drain to waste usually once a day. If the soil is still wet I'll wait a day to water.

If a leaf has a spot, it's noticeable on the underside as well.
For sure, but what caused the spot could be hiding under there too.

Also, not a coco guy but your leaves kinda look like your girls are getting too much water. I didn't think that could happen in coco?!

I know, I was thinking the exact same thing, so I've been experimenting with my water regimen. I'm hoping it's not some sort of disease making the leaves curl like that.
