The new leaves on my indoor Bizzy Lizzies which are forming are growing abnormally. They have uneven edges and look as if a caterpillar has been munching on them. As I mentioned, they are indoors and there is no sign of any bugs anywhere near them. They are not discoloured and the plants looks very healthy otherwise. Any ideas what is causing the irregularly shaped leaves?
