I would just assume that it was overwatering and stress from moving into a new place. Do you have holes in the bottom of your planter? If it is in one? If not there could be water trapped in the bottom bothering the roots.
Do what I do. The finger test. If your finger is wet don't water. Dry then water.
Hope that helps.
Lots of things munch on leaves. Iam having that problem myself in my mini roses
But I can't find a culprit as of yet.
