Jacks Professional 20-3-19 Petunia FeED +Mg Water Soluble Fertilizer MSDS

This product is specially formulated for those chronically iron-hungry crops such as petunia, calibrachoa, bacopa and others. The original Jack's FeED product designed with all three iron chelates, EDTA, DTPA and EDDHA. Our proprietary blend of iron level is unmatched by any competitor and guaranteed to deliver iron at a much broader range of pH over the entire crop cycle. This nutrient profile is also paired with a low phosphorus level to help prevent excessive elongation. It is not recommended for use on geraniums or other iron sensitive crops.

For Use On: Petunia, Calibrachoa, Bacopa

Mixing Instructions
Chart displays the amount of dry fertilizer (oz.) to add to each gallon of water to make a concentrated solution. Please check your injector setting before use.

Mixing Table

Desired N Feed Rate 1:15 1:100 1:200 E.C. Value
50 ppm 0.50 3.38 6.75 0.32
100 ppm 1.00 6.75 13.50 0.64
200 ppm 2.00 13.50 27.00 1.28

Limit of Solubility = 4 lbs per gallon

Important Notes:
E.C. value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. In solution, color will remain consistent.

For best results, use warm water to dissolve product. Jack's fertilizers are made with 100% soluble raw materials that will form a true solution. Some raw materials are slower to dissolve than others. Keep stock tank covered to reduce light and debris inputs.

What crops is Jack's Professional 20-3-19 Petunia FeED designed for?

Jack's Professional 20-3-19 Petunia FeED is specially formulated for chronically iron-hungry crops including petunia, calibrachoa, and bacopa. The formula is not recommended for geraniums or other iron-sensitive crops.

What makes the iron delivery in Jack's Professional 20-3-19 Petunia FeED different from other fertilizers?

Jack's Professional 20-3-19 Petunia FeED uses a proprietary blend of all three iron chelates, EDTA, DTPA, and EDDHA, which allows the formula to deliver iron across a much broader pH range over the entire crop cycle. This triple-chelate approach is designed to outperform competitors and ensure consistent iron availability even as pH fluctuates.

Why does Jack's Professional 20-3-19 Petunia FeED use a low phosphorus level?

Jack's Professional 20-3-19 Petunia FeED is formulated with a low phosphorus level (3% available phosphate) to help prevent excessive stem elongation in crops like petunia and calibrachoa, promoting more compact and desirable plant structure.

Can Jack's Professional 20-3-19 Petunia FeED be used in both hydroponic and soil growing systems?

Yes, Jack's Professional 20-3-19 Petunia FeED is suitable for both hydroponic and soil nutrient applications. The fertilizer is made from 100% soluble raw materials that form a true solution, making the formula compatible with injector-based delivery systems commonly used in both growing environments.

What is the guaranteed nutrient analysis for Jack's Professional 20-3-19 Petunia FeED?

Jack's Professional 20-3-19 Petunia FeED provides 20% total nitrogen (8.04% ammoniacal and 11.96% nitrate), 3% available phosphate, 19% potassium, and 1.34% water-soluble magnesium, along with chelated micronutrients including 0.2% iron, 0.05% manganese, 0.05% zinc, 0.01% copper, 0.02% boron, and 0.01% molybdenum.

How should Jack's Professional 20-3-19 Petunia FeED be mixed for use with an injector system?

Jack's Professional 20-3-19 Petunia FeED mixing rates depend on the injector ratio and the desired nitrogen feed rate. For example, to achieve 200 ppm nitrogen at a 1:100 injector ratio, add 13.50 oz. of dry fertilizer per gallon of concentrate. Jack's recommends using warm water to dissolve the granules and keeping the stock tank covered to reduce light and debris. EC measurement is the best method to confirm fertilizer strength, with 200 ppm nitrogen producing an EC of approximately 1.28.
