Something is eating my yacon leaves.

I can't find any caterpillar under the leaves. There could be millipedes in the container, but I can't imagine they have that level of appetites, besides they prefer dry organic matters. Could earwigs eat this much?

I've been spraying the leaves with my neem oil + peppermint soap and it seems to help a bit, not sure if it fully solved the problem.

I could put a tomato cage over it and use mesh netting, but I don't know if the pests come from outside or within the containers. I have three containers and it happened on all of them.
