MasterBlend 4-18-38 Fertilizer (1 Pound Bag)

Master Blend fertilizers have been the go-to Hydroponic and Garden fertilizers for commercial gardeners for a long time. Their 4-18-38 Tomato and Vegetable Fertilizer provides proven results time after time. Because of the unique composition, it is recommended to use the 4-18-38 together with Magnesium Sulfate (Epsom Salt) and Calcium Nitrate for the ultimate balanced water soluble fertilizer. It is recommended to use Master Blend 4-18-38 in conjunction with Calcium Nitrate and Magnesium Sulfate (also available) in the following recipes. IMPORTANT! Do not mix the 3 components together! Doing so will cause nutrient lockout and all the nutrients will not be available to your plants. You can mix the Master Blend and Epsom Salts together, but not the Calcium Nitrate! Ideally you should mix each component separately in your water until thoroughly dissolved before mixing the next component.
