I can get calcium and magnesium carbonate(pharma grade) and what I am thinking is to use it as a foliar spray to feed the plants. Instead of epsom salt and adding cal to the soil...
Be careful. Unlike primary nutrients or even magnesium, which are very mobile, calcium is not great to apply via foliar means and has potential to cause leaf burn. Much better off applying through the soil.
