Look under your leaves for pests. Could just be some weak cell walls that didn't hold up. Doesn't look concerning if no pests.
Looked around for pests with a magnifying glass and nothing underneath the leaves.

Ya got Thrips. They lay eggs on the top of the leaf, and feed on the bottom. Pluck a leaf, and put it under a microscope, or 60X'x loupe. You'll see em' near the stem veins. They are sneaky little bastards.
I did man I took a few leaves I can't find anything moving anywhere. I should also mention I use UVB for 2 hours a day that should kill anything. I'll take another few leaves and check them out

How clean is the grow space? Could be debris if you aren’t finding bugs.

Best investment I've made,...(well, there's been several), but a 1200x microscope is a great investment. Small bugs are hard to zone in on with a hand held. I think it was like $114.00 delivered on AMZ.

As for Thrips?.... Soak them down in a spray (assuming you're still in veg) with Spinosad (Capt Jacks) and spray upper and lower leafs just before lights out.. Never spray anything during lights on.

Do that, and wait one week, do it again.. they should be gone.

UVB is not going to kill active adults... it will fuck up your grow tho. It kills out your trichs. Don't use that. It's basically like nuking your THC, CBD, and many other terpenes.

I had a bad batch that barley passed pathogens... I used a UVB wand for like 10 seconds on my sample..still failed microbes, but took all my THC, CBC, and Terps to near half... ended up selling it to processors.
UVB increases terpenes and flavonoids, doesn't do anything to thc. Scientifically proven. Trust me on this one. It doesn't destroy weed, if that was the case then all outdoor grows would be trash.

Just going by my labs man..... of course, none of them are solid or reliable.... then again, it could be man made UVC that's messing with it. IDK.

2nd thrips. They leave shiny white marks where they have eaten the leaf. They are small and white.
As mentioned use spinosad. Works a treat!

Everything that isn't shaded. UV is difficult in that sense so you might get a reduction but will never erradicate anything.

Aye they are troublesome. I got mine from store bought plants that were in the house.
Are you far into flower?

3rd vote on thrips!
I alternated between PyGanic and Dr. Zymes eliminator to get rid of them a few months ago.
I treated every 3rd day and it took almost 3 weeks to get rid of them cause they kept coming in on me from outside -_- fuckers
They suck but there are worse bugs to have. Like hemp russet mites.

I could harvest now it's grand but I wanted to push them another week
