CMX is a calcium and magnesium additive.
Used as a prevention of nutrient deficiency symptoms.  
CMX also contains all trace elements (Fe, Cu, Mn, Zn, Mo, B).  
Many deficiency symptoms are actually due to trace element deficiencies

• Calcium Deficiency - Blossom-end-rot
• Upward leaf curl
• Withered flower / fruit set
• Interveinal chlorosis
• Stunted growth rates

Contains 6% calcium, 2% magnesium, 0.2% iron EDDHA (NPK 4-0-0) and all of the other trace elements (copper, zinc and manganese as EDTA, molybdenum and boron).
