Ensure optimal nutrient uptake and prevent deficiencies with Simply Professional Formula's concentrated Cal-Mag supplement. This 100% soluble powder is fortified with chelated iron, making it highly effective and easy to use.

To address deficiencies associated with reverse osmosis water, specific feeding regimens, or poorly buffered coco coir, follow these guidelines:

1. **Nutrient Supplement Usage:**
   - Suitable for Hydro, Coco, Soil, DWC, and Foliar Feeding.
   - Mix at a rate of ¼ Teaspoon (1.25 grams) per gallon of water.
   - Supplement Cal-Mag to achieve an EC of 0.3 – 0.4 (150 – 200 ppm).

2. **Buffering Coco Coir:**
   - Use clean water with low total dissolved solids (< 400 ppm) for best results.
   - Properly buffered coco coir is essential to prevent nutrient deficiencies.
   - Mix at a rate of 1 Teaspoon (5 grams) per gallon of water.
   - Fully submerge coco coir in Cal-Mag solution and soak for 8 hours.

3. **High Performance Reverse Osmosis (RO) Water:**
   - Some RO systems effectively remove all minerals and carbonates from water.
   - Replenish minerals with Cal-Mag Formula before mixing with Simply Professional Vegetation & Transition Formula.
   - Supplement Cal-Mag up to an EC of 0.3 – 0.4 (150 – 200 ppm).
   - Since highly purified water may lead to low pH levels, ensure the pH of the solution is above 5.5.
   - Use a high-quality pH up product to adjust pH, and gradually reach the desired pH target within the recommended range of 5.5 – 7.5.
