DaKine 420 CalMag, 12-2-12, 200 g.

We know that Coco Coir is a very popular because of its high cation exchange capacity (CEC). But if you don’t buffer that growing medium with calcium for strong cell walls and magnesium for chlorophyll production, we may turn yellow in protest. We can also tell you that too much sodium and potassium can cause overdosing, and that’s no bueno. So do us a favor and treat our Coco Coir (or whatever growing medium you use) with CalMag. It’s a delicious 12-2-12 product containing 6% Calcium and 3% Magnesium for consistently beneficial results.

• Water Soluble fertilizer calcium magnesium formula.
• High nitrate nitrogen formula with potassium, calcium, and magnesium for improved quality and color.
