Plant Marvel Cal-Mag 17-5-17, 5 lbs
With 4% Calcium and 1% Magnesium
A favorite of orchid growers. Excellent for tomato and vegetable crops that require calcium and magnesium. Contains all the major and minor nutrients including phosphate, calcium, and magnesium in highly soluble form. The calcium to magnesium ratio is perfectly proportioned so that they will not impede each other's uptake by acting as antagonists. Has a very high ratio of nitrogen in nitrate form.
Easy to use soluble fertilizer. Feeds through the leaves and roots. For potted plants and general use, mix 1 teaspoon per gallon of water at each watering. 5 lb. bag.
