Some of the leaves on the hibiscus have developed a kind of green wart on them. Otherwise they look pretty healthy. The only new thing I have done to them in sprayed them with Miracle grow. I don't think they were there before. It is only on a few of the leaves. Any Ideas and what should I do. Thanks

It looks like Hibiscus erinose mite, a dangerous pest.
It's recommended to cut the stems affected and destroy them. For the rest use a miticide.
Your agricutural department (I don't know how it's called there) can give you more instructions (I guess the first one will be put it in quarantine).
Sorry for the bad news.
