Q:

 What should I do if I have spotted bugs or fungus/mildew on my plants?

A:

 An appropriate treatment should be chosen for whatever the damage entails. If insects are spotted use an insecticide/pesticide or if mold/fungus/mildew is evident use a fungicide treatment. There are many products that are effective for both. Whether using a liquid spray or aerosol fogger, multiple applications are recommended. Avoid using these products in the heat of the day i.e. direct sunlight, active grow lights.
