NITROGEN (N) - Nitrogen is necessary for lush, green, leafy growth. An excess, however, will
promote vegetative growth at the expense of fruit or flowers. Nitrogen is generally applied at higher
concentrations in early growth stages. Use Down To Earth Bat Guano, Blood Meal or Feather Meal.
PHOSPHORUS (P) - Phosphorus will promote big, bright blooms and enhanced fruit production.
Phosphorus is essential for fruiting, flowering, strong root growth and quality seed development.
Use Down To Earth Fish Bone Meal or Seabird Guano.
POTASSIUM (K) - Potassium, or Potash, helps produce strong sturdy plants and quality fruit.
Potassium naturally increases a plants resistance to all types of stress and is vital for cell growth
and carbohydrate metabolism. Use Down To Earth Kelp Meal or Langbeinite.
