Hi
@Ganjagardenner! Neem oil, milk, potassium bicarbonate, garlic, sulfur [...] will do te job. I'd recommend to go with garlic which contains a lot of sulfur. This works best when combined with rubbing alcohol or neem oil, just a few drops of neem oil mixed with crushed garlics, milk and water. Remember to spray at night, or you will increase the risk of burnt spots onto the leaves. Hope this wil help, keep us up-to-date and happy growing 👊
