There are lots of possibilities for the exudate on the trunk. If an injury causes it to leak sap, it dries in a white crystalline form. The gray-greener ones could just be lichens, which are harmless. The leaves though, do not look good. I've included a link to an article with a photo that looks a lot like your leaves. It could be drought stress, salts, high pH, etc., which are discussed in the article. I've also included a sheet on diseases with their symptoms, which you may recognize.
