Though nitrogen still plays a crucial role during flowering, it’s not really utmost needed as compared to the other two nutrients (potassium and phosphorus). Nitrogen induces harsh taste of buds and will decrease the potency of the buds. Thus, high nitrogen content fertilizer is only applied during the last 20-30 days of flowering stage of the plant.
