This recipe gives you a well-draining mix perfect for container gardening, and is easily customized. It's based on amendments per gallon, making it easy to mix small amounts for indoor soil growers.
Here's a recipe based on volume:
5 parts CSPM or 50%
3 parts perlite or 30%
2 parts compost/vermicompost or 20%
I eyeball these measurements with a 5 gallon bucket.
Fertilizer:
Add 1/4 C. dry meal fertilizer per gallon (Kelp, alfalfa, neem, chicken manure pellets, etc)

Lime and minerals per gallon of base mix:
1 Tbsp calcium carbonate (gardening lime, ag lime, oyster shell) or dolomite lime
1 Tbsp rock dust
1 Tbsp greensand (Optional)
Leave out the fertilizer, rock dust, and greensand and you'll have a fine seedling mix.
