The idea would be to know what soil you used, what the PH was and what minerals it had to begin with.
Before any addition of anything but soil.

Correct! As I said I'm experimenting and in some mixes I'm using coir, so if I were to add lime, the PH could go above 7.0 or higher.
The article you pointed to said to add lime 4 months ahead of time, so don't forget to do that
Yeah reminds me a bone meal which takes a few years to become available.
If you really need calcium, as the article points out too, use calcium nitrate.
