"Living Soil"... Am I going in the right direction?

Here's the mix I'm using.

I started with:

1/2 fox farm happy frog
1/4 fox farm ocean forest
1/4 organic perlite

to make 100% and mixed it all together

then I added the appropriate amount of:

worm castings
bone meal
organic potash

so the happy frog and ocean forest are organic and provide base levels of organic npk

the worm castings provide organic nitrogen and microbes
the bone meal gives it phosphorus and calcium
and the organic potash gives it organic potassium

Ive got organic npk coming from multiple sources and the worm castings I understand help the microbe growth and everything to have good chemistry

Am I missing anything? All I can think of is bat guano, should I throw that shit in there too?

Am I on the right track? Any comments?

Thanks!
