Unless you can identify plant issues, and know the how's and the why's of adjusting your soil recipe, I'd go with a commercially available potting soil properly buffered.

Keep it simple, as throwing every friggin thing you can think of at the soil isn't a recipe for success. It's a recipe for abject failure.
