Q.Sum And Substance Hosta Problem?

This can happen for a few reasons-
Diseased soils will produce spots such as this, but it can happen due to pH swings, or nutrient deficiencies, as well.
Too much sun can be damaging to the plant, as well. Make sure that these plants are situated in an area where they will receive quite a bit of shade. They will enjoy dappled light, but never full sun.
