Wind burn?

I’m stumped

I’m thinking light burn

That’s what I was thinking but it’s also on lower leafs deep inside canapy towards the pots

I’m stumped as well

Root rot maby? I only water 2x per day and I run h2o2 and I sanitize my Rez every Rez change...hmmm Iv seen this on every grow Iv ever had never really thought to much of it I do can a kitty that likes to sneak in the tent maby he licked or bit some of the leafs and they are infected?

Root rot has all kinds of symptoms usually all over the plant and I would think with pet damage there would be more tattered leaves.
does it keep getting worse or stay pretty much like the pics?

Hmmmm not to sure just kinda popped up

Some of it kinda looks like thrip damage.
