I cannot see any bugs on the plant at all. Even when i look with a 25x optical magnifier i do not see anything under leaves on stems or the top of the leaves
Luckily my weed is indoor , but outside plants have a dust of de on all..we have sooo many bugs and I not much of a poison person..murdered some catapillars the other day...little shitsI was going to offer ‘grasshoppers’ too...they are doing that to my garden. I just catch them and crush them with my shoe...works great!
I normally think of thrip damage as not eating through the entire leaf, but rather piercing the outer layers (normally under the leaf). This then makes that section of the leaf thinner, so it looks like white spots on the top of the leaf. And most certainly you will see them on the underside with a loupe. (Sure there's a million different kinds, so best to image search on your area.)I would say they're thrips.
Not knowing where you live, makes it hard to know what bugs are around. I'm sure everyone has different grasshoppers. The one I have are pure green (even when large) and while I do see em around a fair amount, they never do much damage. A telltale sign for me is that they poop a clear liquid, that looks like a large water drop When it dries it turns white. Almost looks like PM, but you can see the splatter effect and can rub off. If they're around you should see em. For me they're not a problem and I just kill by hand.
Could also be caterpillar damage. It's been a very busy butterfly season in my neck of the woods (northern CA) and I normally get a lot of bud worms. At this point in the season they'll chow down and you won't see them around (or they're really small). If you see any type of silk (looks kind of like spider web material) around the damage area. They will also leave the bubbled appearance like you have. Bacillus thuringiensis (Bt) is a natural occurring (organic) bacteria that you can buy cheaply at any hardware store that will kill them.

Been Using cal mend by dutch nutrients on the plant already so i shouldnt have and calcium def.Calcium deficiency? Try a cal mag supplement, but include humic acid at t 5-2 humic to calcium ratio. Kelp is a good source of all, or you can mix your own. The humic acid will cause a greater uptake of Calcium and make your plant more resistant to insects and fungus. Make sure you are getting plenty of light.
