I've temporarily solved my problem by bringing back some General Hydroponics powdered
nutrients from a recent visit, but I imagine this will only get me by for a growing season or two, and of course this doesn't help anybody else.
I am in the pre-liminary stages of seeking a long-term option by importing nutrients in greater quantities or finding a customized local option, and selling it, so if anybody is interested in buying, then contact me and I will keep you updated on whether or not I pursue this option.
