i'm sorta wondering why you want to use it..
With your tea and compost it's kinda like making your own top sirloin steak at home, and then wondering if the advertising for mcdonalds is intriguing enough to go buy a hamburger.
I'd stick to your tea and forget about the bottled stuff man.
the first four ingredients on the liquid karma is dolomite, potassium carbonate, fish meal (not hydrolysate), and magnesium sulfate (Epsom salt)
Your compost tea will shit all over that.
Basicly a ph adjuster/ cal/mag.
