A good base soil is
1/3 sphagnum peat moss
1/3 perlite
1/3 quality compost - this is THE most important ingredient in your soil. If you aren't making your own, maybe check out craigslist for someone selling a quality local compost - like worm castings!!!! or organic free range chicken shit or organic steer manure. This is the heart of your soil. Look for it, pay for it, whatever. For the future, make your own worm castings; it's easy and makes a huge difference.
Amendments:
use the mykos you have
use the guano you have
bone meal
kelp meal
oyster shell flour (or dolomite lime) - helps with ph and calcium
glacial rock dust (granite fines -basically dust - from your local quarry could do or azomite is OK)
crab shell meal (if you have the bucks or a local source) - adds calcium and chitin (pest prevention)
You'll need to add a cheap and easy to make banana peel tea for potassium when you go into flower. If you are going to reuse your soil, get greensand; don't waste your money unless you are going to keep using the soil because greensand breaks down VERY slowly.
There are many other amendments that you could use but those will get you through a grow. You may need to reamend part way through with some top dressing - especially some of those quality worm castings (if you got them) and kelp meal...but let the plant be the guide...
When you have more money and time - pick out one slow and one fast source for each NPK and at least three sources for minerals.
