What is the active ingredient in your captain jacks? Is that potassium salts of fatty acids,
spinosad or something else entirely?
Also just a quick warning, you don't want to spray your plants in the sun light. It's advised to do it either at sun up or sun down. This is due to the fact water droplets work as a sort of magnifying lense which works just like when kids would use a magnifying glass to burn bugs or start a fire, concentrating the sunlight into a small area causing it to burn the leaves.
