Neem is great if used regularly. Idk about vinegar, but I do use citric acid in my IPM at low rates for prevention, and higher concentrations for treatment. The neem is good at 5ml/liter with some yucca or a few drops of detergent added to emulsify it-be sure to shake it like your life depends on it, and spray underneath each leaf, as well as the area around the plant outdoors, the soil I mean. Also, spray any nearby non-cannabis plants.
