Well milk has proven antifungal properties
" Numerous studies have shown milk and/or whey to be even more effective at killing powdery mildew than chemical fungicides. In a 2009 study by the University of Connecticut, which tested a milk treatment of 40% milk and 60% water on plants infected with powdery mildew, “the milk treatment provided significantly less disease than the untreated control, and the chemical treatment had equal or significantly less disease than the milk.” Scientists are not sure why milk is so effective, but they believe that when milk interacts with the sun,(UV) it produces free radicals that are toxic to the fungus."
It is also rich in proteins and other vitamins and minerals, the proteins when broken down provide nitrogen mind u not as much as I would like, the medium I’m using is 33% sheep manure 33% castings and 33% promix. I think I messed up my soil base with the amount of peroxide I was using. Also the space I’m growing in is leaky when it rains and as a result anything I leave outside the lighted area starts to grow something aside from itself. I used the same recipe last summer and it worked great.
