MasterBlend fertilizers have been the go-to Hydroponic and Garden fertilizers for commercial gardeners for a long time. The Masterblend 4-18-38 fertilizer was specially developed for fruiting and flowering plants in both soil and hydroponic systems. It can be used alone as a bloom enhancer, or if you would like to use it as an all-in-one balanced formula, it is recommended to use the 4-18-38 together with Magnesium Sulfate (Epsom Salt) and Calcium Nitrate for a balanced water soluble fertilizer. 1 and 5 pounds will arrive in smaller packages. 25 pounds will be in the manufacturer's bag. It is recommended to use MasterBlend 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 MasterBlend 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. 1 Gallon Recipe: 2.4 grams MasterBlend 4-18-38 2.4 grams Calcium Nitrate (15.5-0-0) 1.2 grams Magnesium Sulfate (Epsom Salt) 5 Gallon Recipe: 12 grams MasterBlend 4-18-38 12 grams Calcium Nitrate (15.5-0-0) 6 grams Magnesium Sulfate (Epsom Salt)
