I dont know if this is of any interest to anybody but Montys Plant Foods offers a couple of fertilisers which nearly exactly match the recommended NPK levels in the bloom stage. Also there is a claim that plants do not burn because of some humigin acid thingy that is added to the fertiliser.
There is also a liquid carbon soil enhancer which looks promising. I havent tried any of it out as of yet, but once my order arrives I'll post its level of success.
