Best soil mix?

Hey im trying to get some opinions on the best soil mix. im thinking bout doing one i seen on high times magazine.

4 30 POUND BAGS OF ORGANIC SOIL

12.25 LBS ORGANIC WORM CASTINGS

2.5 LBS STEAMED BONE MEAL

2.5 LBS BAT GUANO

.3 CUP EPSON SALTS

1/4 CUP SWEET DOLOMITE LIME

1/4 CUP AZOMITE

1 TBSP POWDERED ACID.............................................

The recipe was designed for eight 30 lbs bags. But i cut it in half. I havent tried it but i was gonna do it with out the epson salts azomite and humic acid because i dont know where the heck im gonna find that lol. Any suggestions????

I do compost, perlite, coarse sand, worm castings.

10% Perlite
15% Coarse Sand
25% Worm Castings
50% Compost

Its very rich, but wont burn. It has great airation and water holding abilities. It stays loose making it very easy for roots to grow and explore.

Its also pretty cheap and easy.

You can get water soluble powdered humic acid from earthcrew.com at wholesale.

here's mine:
1/3 organic potting soil
1/6 cow manure
1/6 wood ash
1/6 sand
1/6 compost
