Have you tried Gil's Cal/Phos egg shell recipe? I want to try this one of these days:I second this, skip the dolo. It's sht. I'm still have Ca issues with my last batch of soil that I used it in (and didn't crush before hand) and its been about 10 months since I let it rest after mixing it up.
A good source of relatively long-term Ca would be egg shells. I take 25-100 shells depending on soil mass, bake half for a few hours on like 350, crush all of them with a mortar and pestle, then add to my initial mix. I use this in my gardens too.
