Collection: Nutrients PK

PK boosters add extra phosphorus and potassium during flower, on top of your base feed, to support bigger, denser buds. Shop Canna PK 13/14, House & Garden PK 13-14, Atami Bloombastic, Shogun PK Warrior 9/18, Advanced Nutrients Hammerhead, and Intense Nutrients' PK 9/18 Ultra and PK 13/14 Phite. Introduce PK boosters gradually and watch your EC — they're concentrated and easy to overdose.
