I would still go with the diatomaceous earth...it can do in a number of pests. Put it around your containers, around the plants and dust the plants with it.
You could also find a fabric store(or a Walmart with a fabric dept) and purchase some fine Tulle netting(it's very cheap), then drape it over your plants(using sticks or stiff wire for support), securing it around the rim of your pots.
Another option is an insecticidal soap(I use Safer's). HTH

It look like the slugs munched on those. Sorry to say but they look too far gone to have a chance but thats only my opinion.

nooooooooooooooooooooo!!!

there isnt any way 2 save those 2?

If you can keep them out of harms way they will produce new leaves and do fine.

Grasshoppers! or something similar. I found some of my plants like that and saw the freaking little hopper on another plant. ate ALL the leaves off of one of my little plants. But not to worry! the plant now has a bunch of new leaves! yay!

Big chunks bitten out all around the margins of the leaves usually are caused by a large insect such as a Japanese beetle. Slug damage is somewhat similar, but I think the bites are less distinctly shaped. I don't have an example at hand for comparison though.

I will rule out hornworms. They can do large scale damage, but I believe they don't work around the margin like that. They consume an entire leaf at a time.
