A good buddy of mine brought me a jar of this all purpose plant food 16/16/16 along with a jar of bloom 3/20/20. I haven't really been able to find much info on it, but have used it in different ratios to give it a try. Was wondering if anyone else had heard of or used it and what their thoughts and opinions are on it. Also, someone told me to use some magnesium sulfate (epsom salt) along with it. Anyone with any info would be great. Thanks
