MasterBlend 4-18-38 Tomato Formula

Water Soluble Fertilizer

For Continuous Liquid Feed Programs and Hydroponics

Use this fertilizer in conjunction with Yara calcium nitrate (15% N, 19%Ca) and Giles magnesium sulfate(9.8%Mg, 12.9%S) to formulate a complete fertilizer solution. 

MasterBlend Tomato Formula 4-18-38 is completely water soluble and high purity, making this fertilizer suitable for all continuous feeding programs such as drip feed and all hydroponic systems.

Mixing rates:

Established plants: Mix 8 oz. of Master Blend 4-18-38 in 100 gallons of water, along with 8 oz. of calcium nitrate and 5 oz. of magnesium sulfate. For small volumes use 2.25 grams Mater Blend 4-18-38, 2.25 grams calcium nitrate and 1.5 grams magnesium sulfate per gallon of final volume working solution. This will give a nutrient profile of approximately:

116ppm N - 47ppm P - 188ppm K - 41ppm Mg - 113ppm Ca - 58ppm S

2.4ppm Fe - 0.3ppm Zn - 1.2ppm B - 0.3ppm Cu - 0.06ppm Mo - 1.2ppm Mn - 12ppm Cl

Transplants: Mix 8 oz. of Master Blend 4-18-38 in 100 gallons water, along with 6 oz. of calcium nitrate and 4 oz. of magnesium sulfate.
