Ask yourself why did you do it?, Was it needed?, and what was it purpose if it was needed?
Have you ever noticed when your get salt water on your stuff the salt shows up after it dries. this is the same process. If you spray a dissolved solid in water and the water evaporates. the solids in this case sulpher is going to show depending on its concentration in the original spray. its how most topical sprays work, the presence of the product on its leaves is the deterrent.
