MasterBlend Lettuce Formula NPK 8-15-36. MasterBlend fertilizers have been the go-to Hydroponic and Garden fertilizers for commercial growers for a long time. Their 8-5-36 Fertilizer (Lettuce Formula) provides proven results time after time. This formula has been specially formulated to use with Hydroponic lettuce crops. Because of the unique composition, it is recommended to use the 8-15-36 together with Magnesium Sulfate (Epsom Salt) and Calcium Nitrate for the ultimate balanced water soluble fertilizer.

  • MasterBlend Lettuce Formula 8-15-36 is fully Water Soluble
  • Direct from MasterBlend - Fertilizer for Tomatoes and Vegetables
  • Highly concentrated!
  • Master Blend fertilizer is perfect for Hydroponics and Soil gardens

It is recommended to use MasterBlend Lettuce Formula 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.

Please note that using a scale that is accurate to grams is the best way to measure.

11 grams Masterblend - dissolve thoroughly

8.5 grams Calcium Nitrate- dissolve thoroughly
