Hi
So the majority of bugs that leave holes like that aren't tiny, they're visible, caterpillars, inch worms, grasshoppers etc.
I've gotten some holes and cuts from clumsy fingers and fingernails. Otherwise sometimes the plant could get burnt and the leaf get dry spots that flake away.
I would just continue to scout just in case something did get in and is hiding. And just keep giving TLC and watch to see if it continues.
Happy growing.âď¸
