NFTG: Demeter’s Destiny, Gallon

Many production problems originate with too much nitrogen and potassium and not enough available calcium and phosphate. Calcium is the “queen-king” of all nutrients, aiding enzymatic action, feeding soil microbes, improving nutrient availability and cell wall integrity, encouraging solid stem growth (vs. hollow in a calcium-deficient situation) and preventing stem breakage. Calcium promotes smooth, sweet, aromatic produce, and generally leads to healthier, more vigorous growth.
