Anyone do a spider mite spray w/epsom salts for sulfur content?

Epsom salts are cheap and contain magnesium sulfate and about 12.8% is sulfur. I know some mite sprays use sulfur. Anyone ever use Epsom salts for spider mite spray concoction?

No. But, I've been reading about people who boil up a whole batch of ultra hot peppers and spray that on the litttle fuckers.
