The first time I got rid of aphids with nutrition it happened that I had a foliar feeding program that contained molybdenum magnesium and boron and I had put gypsum in the soil so sulfur was not included in the foliar program. then the aphids arrived and I didn’t understand why, I added epsom salts ( magnesium sulfate)to the foliar and in 24 hours the aphids were gone, the remaining ones were dead. I follow synchangel and I asked him how he explains this experience but he couldn’t answer. I don’t care if peer reviews say it’s not possible if the facts prove it is. the brix level before foliar was 5 after 12.
