Master A - 5 Gal. - Humboldt Nutrients (HNMA420)

Humboldt Nutrients Master A&B is a premium two-part fertilizer program designed for all plants made with non-toxic, high quality ingredients. Humboldt Nutrients has formulated this vigorous 2-part nutrient solution for use on any plant, in any growing medium and contains no EDTA s. The Humboldt Nutrients team of chemists and agronomists emphasize balance and consistency with all our formulas. Master A and Master B are formulated to provide your favorite plants with higher absorption of nutrients, vitamins, minerals and trace elements. The Master A and Master B series stands apart from your standard base nutrient line by making macro and micro nutrients more available to your plant. Used in conjunction with Humboldt Nutrients powerful additives we assure that your yields and quality will increase so dramatically that your friends will call you, simply, The Master. Guaranteed Analysis Total Nitrogen (N) .. . ..4.00% Ammoniacal Nitrogen 0.80% Nitrate Nitrogen 3.20% Soluble Potash (K20) .. .3.00% Calcium (Ca) . .1.70% Molybdenum (Mo) 0.0008% Zinc (Zn) .0.05% Water Soluble Zinc ..0.05% Derived From: Ammonium Nitrate, Potassium Nitrate, Calcium Nitrate, Sodium Molybdate, Calcium Carbonate, Sodium Borate, Iron, Zinc, Manganese, Boron and Molybdenum. Directions: Fill your reservoir with clean water before administering any nutrient or additive. Make sure that the water level in your reservoir is sufficient enough to effectively flood your desired area or table. Potential nutrient lock-out can be avoided by adding Master A to your reservoir first and thoroughly mixing it in, then add Master B. Never mix these nutrients together in their concentrated forms. After adding in each nutrient adjust the pH of your reservoir between 5.5 and 6.5. Keep the water temperature in your reservoir between 65 and 75 F. Drain and clean your reservoir and pumps at least once a week to prevent any salt buildup. Avoid storing in direct sunlight and protect from freezing.
