This diagram shows that Sulfur stimulates Calcium, Molybdenum and Copper availability to the plants and that Zinc and Molybdenum both stimulate Sulfur. So I don't see an issue BUT if you saw something being locked out by excess Calcium, Molybdenum or Copper then perhaps the sulfur is the actual cause.

As we can see in this chart, excess Calcium for example, could limit potassium uptake.
Every element has it's limits so how much sulfur can we have without issues? I really don't have that number.
