Grotek Cal Max

Grotek Cal-Max is amazing for amending coco coir based media, with fast acting nitrogen and a strong calcium source to assist in buffering coir’s inherent imbalance.

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

• Corrects Common Nutrient Deficiencies
• Excellent for Coconut Coir
• Use as Foliar Spray or Root Drench
• Alleviates Nutrient Deficiencies in Coir-Based Medium.

A rapid source of nitrogen and magnesium to support chlorophyll and protein development, which quickly re-greens plants low in nitrogen. Chelated iron adds more deficiency fighting power for lush green growth. Added calcium supports plant strength and assists in times of peak growth. During periods of peak growth or high temperature, calcium can be a limiting factor. This formula is designed to drive calcium movement to help avert associated plant damage. Even with sufficient calcium in the soil, high temperature and humidity may hinder plants from absorbing enough. Consider using a foliar application at that point to address the issue.

Application Rate:1L makes 800L of solution. Soil/Soilless: Mix 5 ml per 4L (1 tsp per 1 gal) of water. Use as required. Water Culture: Mix 5 to 8 ml per 4L (1 to 1.5 tsp per 1 gal) of water. Use as required. Foliar: Mix 10 ml per 4 L (2 tsp per 1 gal) of water. Use as required.

Note:Apply as a foliar spray for fastest recovery from nutrient deficiencies. Excellent for pre-charging coco coir.
