wow I see how you got steered wrong, I don't care for their ph up and down solutions either.
Dolomite lime is a natural organic source for calcium and magnesium and helps stabilize PH as well.
"dolomite and dolomitic limestone are added to soils and soilless potting mixes to lower their acidity and as a magnesium source" source wikipedia
Having said all that there is this interesting perspective on soil amendments for balancing PH http://gardenrant.com/?guest_post=please-stop-liming-your-soil-based-on-the-ph
So it seems to me starting with a good solid organic soil base should be the proper way to ensure all available nutrients are balanced in the soil to begin with.
