Dying fan leaves, help!

SO I went to visit my garden today and found that while most (5) of the plants were doing very well, with a couple doing extremely well-- there was one plant that had most of its leaves shriveled up and dead, and another that exhibited this behavior on its lower branches. A third plant also had many little brown dots on the leaves--which i'm guessing is related to the other two plants' problems. Is this possibly spider mite damage? What is going on here?
