Best general purpose, all encompassing, treat-and-prevent-pretty-much-EVERYTHING neem oil brand and usage routine? I have a wide variety of indoor plants and I suspect that several may or may not have certain pests/diseases ranging from fungus gnats/spider mites/scale/aphids/thrips/mealybugs/powdery mildew.
