Is this a nutrient, environment or pest problem??

Coco grow, PH buffered nutrient, LED light. 80F 55% RH.

I used a macro lens to look for bugs

Ok...maybe I should give that a try. Just need to find one that will work with Mantis. I was told to add cal-mag to water, then add Mantis and look for any particulates, and if none present, then it should work. When I was at the shop there were too many different types of cal-mag.

Are you running a humidifier in your tent?? I'm not shure so take with grain of salt but looks like the start of mold, yes it's dry but I found in my situation a humidifier makes things worse, in winter grow hardy strains keep them wet and let them work thru it, at most I put a bowl of water in tent and let evaporate Pic 1 dark devel auto at week 3, Pic 2 either critical or big devel xl not shure witch bean popped, Pic 3&4 strawberry mango crumble.

Humidifier is outside of the tent. It doesn’t look like mold though. More like something is eating away at the green flesh on the top of the leaf. Like if I dripped plant eating acid on it lol.
