I've noticed that the leaves on my tomato plant look like something has been eating the leaves. There are big holes in the leaves. Kind of looks like someone tore up pieces of the leaf. So, the leaf looks like swiss cheese, or there are big torn out pieces.

I would post a pic., but I haven't figured how to do that yet.

Does anyone know what the culprit might be? I'm growing my plants in Earthtainers outside my apartment building, against a wall. I did not have this leaf problem before when I was gardening in another part of town. So, this is new to me.

I want to know how I can stop this from happening! I sprayed some organic stuff that's supposed to kill bugs,etc. But, not sure if that will do it.

Thanks.
