The aluminum sulfate isn't organic...neither is the super phosphate. Not really a problem because the bone and blood meal supply the same thing, I think (I am assuming the a.s. provides N).
There still isn't anything to supply K (that's what the kelp meal is for) so you might have to go online to order. Another option, which gives you a much higher rate of K, is sulfate of potash, or alternatively, sul-po-mag (sulfate of potash magnesia)...you might have to do a little searching on the web to find it, but I was looking for the stuff for my farm a while back and was able to find online purveyors of it. Check out
this page to get you started. Careful though, it's hot for an organic, despite what they say about it being hard to burn with.
I would also highly recommend getting some kelp or seaweed extract product as well, as it contains high levels of growth hormones and trace minerals as well as being very gentle.
You can use the black cow as the compost and maybe add in a little more if you can't find any worm castings. Don't go higher than 20% though. BTW my first grow was fertilized only with composted dairy cow manure and I got some very nice weed out of it, thanks for asking.
