Nova MagPhos 0-55-18+7MgO is a premium fully water-soluble fertilizer supplying your plants with a high phosphorus and magnesium content, plus potassium. It will get your plants off to a flying start in life and crank up their chlorophyll levels. We’ve used our exclusive technology to ensure you get high quality and purity: it’s one of our most concentrated formulas. It’s unique because it’s slightly acidic, even with the large amounts of phosphorus and potassium it packs. Ideal for crops that need plenty of magnesium, such as cucumbers, peppers, tomatoes, or leeks, as a foliar spray or with a fertigation system. Our free-flowing crystals dissolve quickly and easily, and they’re chloride- and sodium-free.
