Cal-Max™ works to charge soilless media and bring plants back from common minor deficiencies associated with nutrient imbalance, rapid growth, or overly humid conditions. A must for growers using coir based soils. Available nitrogen stimulates chlorophyll and amino acid production to quickly re-green starved plants. Chelated iron adds more deficiency fighting power for lush green growth. Added calcium helps to strengthen the plant and assist in times of peak growth.
