General Information


Nutri-Grow Magnum is a concentrated nutrient solution containing, in highly soluble form, certain elements beneficial to plant growth, rooting, root development, flowering, transplant establishment and, with sufficient nitrogen, may improve color development when applied as a properly timed foliar or soil application. Application to turf may improve resistance to traffic if potassium is not adequately supplied by the soil medium. Follow manufacture's recommended directions for use. Applications of Nutri-Grow Magnum should be part of a fertility program based upon soil and tissue testing data and is intended for use as a supplemental fertilizer treatment.


Nutri-Grow Magnum is compatible with most commonly used foliar pesticides, chemically neutral fertilizers and micronutrients. It is not recommended to use this product with surfactants or adjuvants that lower pH. AVOID MIXING with oxidizing chemicals including, but not limited to, chlorine, hydrogen peroxide, ozone and other sterilants. USER ASSUMES FULL RESPONSIBILITY to ensure tank and plant compatibility when tank mixing with other products. (See APPLICATION PRECAUTIONS section.)

Limitations, Restrictions, and Exceptions


Nutri-Grow Magnum may be applied to the soil by all types of soil spraying/injection equipment and through certain types of irrigation systems. Refer to the IRRIGATION SYSTEM APPLICATION section. (See APPLICATION PRECAUTIONS section.)

Infrequent Applications

DO NOT exceed a maximum product concentration of 0.33% volume/volume. Note: A 0.33% volume/volume solution is approximately 0.85 fl. oz. of Nutri-Grow Magnum per 2 gallons of water. (See APPLICATION PRECAUTIONS section.)

Continuous Feed (Fertigation) Applications

DO NOT exceed a maximum product concentration of 0.03% volume/volume. Note: A 0.03% volume/volume solution is approximately 0.08 fl. oz. of Nutri-Grow Magnum per 2 gallons of water. (See APPLICATION PRECAUTIONS section.)


Applications of Nutri-Grow Magnum to the soil can be made through certain irrigation systems including, but not limited to, low volume systems (e.g. micro sprinklers, drippers, drip tape and fanjets) and typical sprinkler systems (e.g. solid set, pull and hand move). The specific injection equipment and irrigation system must conform to all federal, state and local regulations pertaining to the fertilization of plants through an irrigation system. Accurate and properly calibrated injection equipment and an irrigation system that is operated at maximum distribution uniformity will help avoid plant injury and/or product ineffectiveness. For best results, apply Nutri-Grow Magnum toward the end of the irrigation set and allow sufficient time for the product to be flushed completely out of the entire irrigation system prior to turning off the irrigation water.


Due to the continuous development of new varieties of each of the many different ornamental plants, it is recommended that prior to the first use on a particular ornamental variety, the grower evaluate plant response(s) by treating a small sample of plants (6 to 10) with the product at the recommended dose(s). Allow sufficient time after application of the product to determine if there is going to be any undesirable plant response(s), including but not limited to stunting and/or leaf burn.

DO NOT tank mix Nutri-Grow Magnum with fungicidal copper products or apply the spray solution to plants that have been or will be treated with a fungicidal copper spray within 10 days of the planned Nutri-Grow Magnum application.
