In looking closer at the Jack's Classic container, It says J. R. Peters, Inc. Is this the same as Peter's which I have seen referred to in looking at older posts? Thanks again,

There is Peter's specialty African Violets and it is 15:36:14 or something like that - and it is better. I think Jack's balanced has urea. Thing is - the manufacturers of these fertilizers sold their businesses to one another and somebody else, so it is not the same recipe. Since urea is way the cheapest nitrogen source - the recipes eventually migrate towards urea for financial reasons. If you grow in 1:1:1 mix - it is soil free and it doesnt have the bacteria necessary to convert the urea into plant accessible compounds. If you grow in a heavier mix for bottom watering - this bacteria can be present and it will work. I know that Pat's Pets were selling the inoculant of this kind of bacteria some time ago so you could just add it - and you have microorganisms working for you. I heard that because of the age and health issues they are wrapping up their operation - and this is very sad. I think if you investigate on Internet - you possibly will be able to find a similar product - and then you can use any balanced fertilizer.

Good Luck
