Well, if they're notin flowering yet you can use some pesticides. or you can use a homemade pesticide. 15 crushed asprins and a gallon of water. mix it in and upt it in a spray bottle and spray your plants. You can't "grow your leaf holes back" but yeah. I'd clip the really bad eaten ones that way your plant isn't focusing much to tyr to grow those leaves. Other than stopping them like i said there isn't much you can do. GOod luck with them man!
