Cutting Edge Solutions Uncle John’s Blend 0-0-2
Cutting Edge Solutions Uncle John’s Blend 0-0-2 is a concentrated liquid potassium and iron supplement designed to support nutrient mobilization, plant metabolism and healthy development throughout the complete growth cycle. Although suitable for every stage, it becomes especially valuable during flowering when plants require efficient nutrient movement and carbohydrate metabolism.
Uncle John’s Blend works alongside complete base nutrients in hydroponics, drip irrigation, coco coir, soilless media and soil. Its versatile formula can also be applied as a foliar spray during vegetative growth and transition.

Recommended Mixing Order
- Begin with clean water.
- If using Bulletproof Si or another silica supplement, add it first and mix thoroughly.
- Add Micro and mix well before adding the remaining base nutrients.
- Add Uncle John’s Blend separately and mix thoroughly.
- Add other compatible supplements individually.
- Measure EC and make the appropriate final pH adjustment after mixing. Follow the special pH instructions when using Plant Amp.
Important: Never combine undiluted nutrient concentrates directly. Begin with a reduced concentration when feeding young plants or sensitive cultivars, and monitor plant response before increasing strength.
Uncle John’s Blend is a nutritional supplement and does not replace a complete base fertilizer program. Results will vary according to plant genetics, environment and overall crop management.
