Equinox This essential component is the base plant food, providing copious amounts of Nitrogen, Calcium, and complementary elemental traces. As the core of the New Millennium Fertilizer System™, Equinox is concentrated and refined to yield a product that is workable in most types of systems and low in residual salts. Note: SEASONS (PART B’S) ARE MEANT TO BE USED IN CONJUNCTION WITH EQUINOX (PART A) IN A 1:3 RATIO! Consider this PART A and the one constant that will always be part of the plant growing cycle. Recommended to be used in conjunction with the seasons (PART B – i.e. Spring, Summer, or Autumn.) in a 1:3 ratio. Example: 1 tsp per GAL of Equinox with 3 tsp per GAL of Summer. Calcium and Magnesium supplement.
