I have an otherwise sprawling plant, but is does have that same white splotchy, spidery substance all over the stalks and stems. Very little on top or bottom of leaves. No red mites that I can detect anywhere. Is this the same malady you reference in your article, and will the treatment you suggest rid the plant of these issues? How often is that treatment required?

If this white splotch is a web then this could be Spider mites. If it is just white powdery spots then it will be powdery mildew. The treatment will work for both, though. You can apply every few days, or as needed for tougher infections.
