your pics have catapillars on each leaf, the marks are theri tracks, but you have 2 cattapillars on those leafs theri. they are som what clear but you can see em on little one one big one, you need bug spray, home depot or wallmart or a hydro stor will have some thing for cattapillars, just ask them for cattapillar killer. neem oil will keep em away but not after you have them you need incecticied.

you also have fungus groewing on theri too, probly from the weakend state that the cattapillar casued, uses fungicide with sulfer.

you need 2 things now, fungicide and catapillar killer, safer soap and cattapillar killer, any hydro stor will have them. it is to late for neem oil neem is a preventative you need to kill this or you will start to get black mold, then death to the plant comes next. expect black to start settling in, this can not be leaft alone your plants are dieing. you need sulfer fungicide and catapillar killer. if you look online ace hardeware sells safer soap, and almost every garden store has incecticed for catapillars.

I have erd pyrytheum will kill both but I have no experiance with pyrythium
