Cal Mag Max 7-0-3
with 4% Calcium and 2% Chelated Magnesium

Green Industry professionals wage a constant battle to correct Calcium (Ca) and Magnesium (Mg) nutrient deficiencies that occur in plants. Symptoms of calcium and magnesium deficient plants include:

  • Immature development and deformity of the plant.
  • Calcium deficiencies most often occur in the newest growth of a plant. The leaves and new tissue of the plant will curl, twist, and eventually fall off.
  • When a plant is deficient in magnesium, it is the older, more established leaves that are first affected. The plant will become chlorotic, with the leaves changing color beginning as a reddish brown and changing over to yellow. The end result is that the leaves curl and eventually drop off of the plant.

To prevent and correct these deficiencies, a 2-to-1 calcium-to-magnesium ratio product is most often recommended. Growth Products' Cal-Mag Max (7-0-3) fertilizer with 4% chelated calcium and 2% chelated magnesium fits the bill perfectly. It is quick-acting and easy to use.

Cal-Mag Max is great for all classes of horticultural plants, including ornamentals, trees, shrubs, plants, turfgrass, etc.. When applied as a foliar spray, it provides almost immediate correction of calcium and magnesium deficiencies. Cal-Mag Max can also be applied to the soil, as a supplement or in alternation with other fertilizers.
