Cutting Edge Solutions®


NPK Value:  0 - 0 - 2  

Uncle John’s Blend™ supplies potassium along with iron in a unique and proprietary formula. Potassium activates enzymes essential for plant growth reproduction and carbohydrate metabolism.

Uncle John’s Blend™ is formulated for use in hydroponics, soilless, continuous feed, drain to waste, and for use in soil. Use as a foliar spray to reduce transplanting stress and to correct potassium deficiencies in flowering plants.

Uncle John’s Blend™ can be applied at every watering in conjunction with any Cutting Edge Solutions® products, or other commercial hydroponic nutrients.

Directions For Use:

This is a highly concentrated solution. Never mix undiluted concentrates, as this may result in nutrient lock-up. Add each nutrient consecutively, allowing ample time for each concentrate used to thoroughly dilute and mix into the water. If preparing a nutrient stock tank, to be used over a period of time exceeding 24 hours, you must aerate nutrient reservoir regularly.

Shake well and measure carefully using a milliliter measuring cup. If using Micro 6-0-0™, add Micro 6-0-0™ first to water, then other nutrients. After nutrients are mixed in water, adjust pH to 4.5-6.5. If your pH naturally falls within these parameters, pH adjustment is not necessary.

Monitor ppm and EC in reservoir and top off with fresh water as needed. Reservoir temperature should be 60-68 degrees F.

Do not store product in direct sunlight. Do not freeze.

Uncle Johns Blend™ is designed for use in hydroponics, soilless, continuous feed, drain to waste, and for use in soil growing applications.
