Help My Plants Are Dieing

I went to go check on my outdoor plants and i figured i may have given them to much nutrients so it burned some leafs o well big deal but when i went back this time my leafs all have little browm sports on them and holes throughout them looks like the plant is getting eaten by some insect the top leaves are fine but from there down all have this problem any ideas? pictures coming soon.

May be pests, get some neem oil from walmart.

also lemme see some pictures if you get a chance and describe your setup.

It turned out to be to much nutes lol they are recovering fine now.. but i found alot of bugs on them...snails (2) were on the one plant so i yanked them off i also seen a spider which i left because i figured he would eat the bugs i seen on the leaves little black things not sure what they were. I bought neem oil for the next time

the lil black ones might be spider mites.
