FOUR-WAY MIX:
1 part compost.
1 part top soil.
1 part perlite.
1 part "manure".*
Don't use "Backyard Dirt", use "Store-bought"! All 4 ingredients are redily available at Lowe's, Home depot, Ace Hardware, etc. For each gallon of "Mix", add about 1 or 2 Tablespoons of Dolomite Lime.
For Veg:
You can add a little "regular" Fish Emulsion (5-1-1) and/or "Mexican" Bat Guano (high Nitrogen), as a "Vegging" tea.
For Flowering:
You can add a little "Morbloom" Fish Emulsion (high Phosphorous) and/or "Jamaican or Indonesian" Bat Guano (also high Phosphrous), as a "Flowering" tea.

* Nothing too strong or fancy - the "Manure Part" should be about as potent as "regular", composted steer manure. I use some stuff called "Barnyard Blend", from Gardner & Bloome (I think Kelogg's distributes it)
