Description
Just as the name suggests, Jack’s All Purpose 20-20-20 is a balanced formula applicable to a variety of growing material. Its 1:1:1 nutrient ratio makes it good for almost any stage of plant growth. The design of the formula uses nutrients that provide strength to the plant, as well as, lush green growth. It can be used as a constant liquid feed or periodic feed, alternating with water or rain to provide the plant with a boost of balanced nutrition.Preferably, it should be used on soil-based media, rather than on soilless media, primarily during warmer months, indoors or in warm-climate regions. These environments allow the roots to take up the nitrogen sources most effectively. Long-term use of high Phosphorus formulas can lead to plant stretch in some plant varieties. Therefore, it is recommended when using this formula over long periods (greater than 3-4 months) of plant growth, alternate with a lower Phosphorous source such as rainwater, calcium nitrate or other lower phosphorus fertilizers.Application of this fertilizer can be used as a root drench or foliar spray. The nutrient package in the All-Purpose 20-20-20 is designed for optimum absorption by the leaves when sprayed at the recommended rates; however, a root drench is just as effective and will leave little to no salt build up in the media.How to UseFor small volume mixingDissolve the following amounts in 1 gallon of water.
