You have a bad spidermite issue, it sounds like! This is devastating, and usually fatal by this point.

You may be replacing the tree soon. In the future, you will want to catch them as soon as you see signs of spotting or webbing. This article will help: https://www.gardeningknowhow.com/plant-problems/pests/insects/spider-mite-treatment.htm
