I use homemade "Mel's mix" from the square foot gardening guru.
I found sq ft too jungle like but like the mix.
Basically 1/3 of each of the following:
Perlite
Peat Moss
Compost manure - differing manufacturers of this.

Dump similar amounts of each by volume on a tarp and flip back and forth several times. Then load your pots or raised beds.
I use Texas Tomato food with it and it works well.
