I can't see the photo clearly, but I do notice what may look like scale. This insect has many species that classify them as scale. They all vary in appearance, from flat and tan, to large and black or red, to white and woolly looking. They are all hard to treat. I see signs of leaf curling a little. That and a few possible forming spots, which, along with the sap, leads me to believe scale insects to be the case.

You will want to remove as many as you can, then treat with something like neem oil.

This one is, specifically, for lemon trees, but used to show differences in appearance.
