Unlike generic ag water-soluble fertilizers, the Sensi Professional Series delivers precise ratios of micronutrients for each phase of plant development. During the grow phase, your plants will absorb more calcium, iron, manganese, and boron, and LESS nitrogen, potassium, zinc, and phosphorus. And for a bloom phase packed with floral productivity, they’ll uptake MORE nitrogen, potassium, and zinc (and a tad more phosphorus), and LESS calcium, iron, manganese, and boron. Only our water-soluble fertilizers hit this shift to unleash peak performance in your crops.
