NITROGEN (N): Nitrogen is important for growth and immunity. Without nitrogen, the plant will not be able to grow or produce immunity.
PHOSPHORUS (P): Strengthens root systems, capacity for seed creation, disease resistance, and pest prevention. Improves flowers and blooming. Also strengthens tissues and flavors in edibles and veggies. Without phosphorus, plants will not be able to produce sweet fruits.
