Advanced Nutrients AN Sensi Coco Grow B Liter

The coco coir medium naturally attracts and binds to calcium and magnesium. This means your average nutrients will have a greater percentage of their Ca and Mg bound to the growing medium and not transported to your plants (where you want them) ... potentially starving your precious crops. What's more these specially formulated Coco Coir nutrients account for the high levels of potassium already present in Coco Coir so you avoid any possibility of potassium toxicity. That said, the formula still contains the powerful ingredients that make it a proven grower's favorite.
