I know it says no burning yet I did burn my plants pretty badly even with adjusting the pH the largest dose I fed was 10 ml per gallon. I've seen people get good results but I couldn't figure it out... The pH of the emulsion is around 4 to 4.5. I don't know why they cook it , but uncooked has no nitrogen. I mix it in the soil and also put in 1 tablespoon per gallon of water and shake it up to feed as a tea once a week, some of it is soluble in water. I'm trying to find a cheap fert too and this seems to work well.
