Truth be told.
I didn't think of that...
EDIT:
And here's some knowledge on Dolomite Lime:

yes 2 tbsp per gallon of soil of lime. plus extra magnesium. gypsum and oyster shell are excellent ca, su sources. how many examples do u need?

i dunno about this gypsum. I heard it might not be conducive with the other ingredients. I heard people say it was bad because it is plaster or some shit. ?

Is Dolomite a reasonable source for Ca and Mg? This was debated by some experienced folks here recently. https://www.rollitup.org/subcools-old-school-organics/454914-dear-subcool-what-kind-powdered-2.html
What I gathered from the discussion was that Dolomite does not break down fast enough to be considered the major source of Ca and Mg. That's what I took away from the discussion, anyway.

The finer it is the faster it works. From what I understand people use it more to stabilize the PH and the rest is icing, but then again I may be wrong.

look for pulverized dolomite lime rather than pelletized dolomite lime. the pelletized lime is coated and has a brown color and somehow spikes up ppm. pulverized is a fine white powder and sold at lowes in 40 lb bags for $4.
dolomite lime can help stabilize ph and in the process provides a source of cal mag. this is especially important if you are watering with R/O water because the calmag was stripped out. on the other hand some organic soil growers believe that ph control is unneccesary. assuming your water ph is reasonable i agree with that and I have not checked runoff ph in over a year.

I use it mainly for the pH. I have had to use some epsom salts early on, but the Ca seems to be available pretty quick, the Mg a bit later.

I am using the SuperSoil with Rootz and making sure the mico-life is active and balanced. If that's the case, the plant determines the soil pH. The more people that can come to realize this, the easier this all becomes. If doing a balanced organic soil, pH balancing the water is futile and a waste. If in doubt, read the latest edition of Teaming With Microbes.

is this the same rrog from icmag? in a living, native, soil i would totally agree with your assertion that organics phs itself. but in a peat/coco mix i think ph balancing has its place. peat can become really acidic even when utilizing aact.

Hmm i dunno bout you but that looks like powdered cal/mag to me
