How much to mix in??

I will be doing an outdoor grow next year and i have bought a bunch of soil addaments to make my soil organic.. and the best it can be for my girls..

I wanted to know how much of what to mix into 9 (10 gallon holes..)

the supplies I have are:

-30L of Worm Castings
-35L of Humix Shrimp Compost
5x- 85L bags of Premier Pro-Mix, Potting and Seeding Mix
-18L of fine Wood Ash

can anyone help??

bumpp........

do what i do fill the holes with fert free soil and feed them your self.

I also have Fox Farm= Big Bloom+ Tiger Bloom+Grow Big for when the plants need a boost...... But can someone please give me some type of formula in order to mix a good soil for my plants? How much of what would be perfect.. (or some type or ratios..)
