[dolomite lime]
Your first guess was to add 2 cups of dolomite per plant. That seems high
to me. The calcium would be fine, but it might raise the pH more than
one would want. So I suggested 1 cup per plant instead (which still seems
a bit drastic, but comparing to an Earthtainer, perhaps it would be just
right; you do need to compensate for the peat, which is around pH 5
usually).

I was not thinking you would overdose on magnesium with the dolomite
*and* sul-po-mag both being fairly slow-release, but you probably do not
need epsom salts the first year.
