Calcium Acetate....also very cheap.....its the magic ingredient of "Flowering Calmag"
Then you can use Magnesium Sulphate to avoid the Mg Nitrate

If you are growing in peat. You can top dress with Dolomite lime. Peat is quite acid and the lime will sweeten it a little but not enough to mess things up.
40 grams of Dolomite lime per gallon of peat turned in before planting should get you threw any grow. It's slow release. You can also top dress with it if needed.

In an organic living soil.
Bone meal is the key here.
