Mixing Table

Desired N Feed Rate 1:15 1:100 1:200 E.C. Value
50 ppm 1.13 7.50 15.00 0.60

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.

Great quality and price, true to size, and comfortable fit
Size: 32W x 30L, Color: Medium Vintage
Nice jeans--very close in quality to my more expensive Wranglers. And they run true to size, which is a real bonus in today's unpredictable clothing markets. The flexibility of the material makes them very comfortable, whether you're walking or sitting. Good job, Amazon Essentials!

The Best Black Slim Jeans for the Price
Size: 32W x 33L, Color: Black
This is the second pair I bought, this time in Black (32W x 33L). The size and fit are the same excellent slim cut as the medium wash version. The Black is a nice, solid color that looks semi-dressy. The stretchiness is perfect—it makes these incredibly comfortable to wear all day. The material is soft and light for denim. For functionality, they are easily dressed up or down. As for long-term durability, based on my medium wash pair, they hold up very well, resisting bagging out in the knees and seat. Highly recommend this exact fit and material combination.
