What s wrong with my leaves

Most of the bug damage I see results in patterns that look more like a series of dots (similar to whatever staked plant you have growing in the red/orange pot, which on a balcony, might be moths laying eggs and their young feeding on the leaves) and/or squiggly lines. Damage like the one in the picture above has usually been mold/fungus related (at least in my experience), which wouldn't be surprising since you describe getting a bunch of rain lately. Good news is that neem oil is a good first step for either issue (I would spray all of your plants, even if you don't see an issue). I would also recommend removing and disposing of all impacted leaves (including your other plants), and wash your hands afterward. If there's any way to space your plants out more, that would also be ideal (but I can see you're on a balcony). Since you do have signs of bugs feeding on some plants, check all of them for any signs of eggs and young (look under leaves), and remove these leaves as well (if they're on the stem crush bugs and/or scrape eggs off). I would recommend spraying a couple times, once every three days, or after any rain or heavy dew. Hope this helps and happy growing!
