PK by Bloom is the range's dedicated PK booster for that window: a concentrated 0-19.5-21 phosphorus and potassium supplement made from phosphoric acid and potassium hydroxide, run at 1ml per litre every feed through peak flower and stopped for the final flush. It's the heavy PK hit that Phat deliberately isn't, it runs alongside Ooze, and it sits on top of your base nutrients. It's a straight mineral feed, so it adds EC: watch your runoff and back off if leaf tips start to burn. A litre makes 1,000 litres of feed.\u003c\/p\u003e\n\n\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 1rem; margin-bottom: 2rem;\"\u003e\n\u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n\u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eThe range's real PK hit\u003c\/strong\u003e\u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003e0-19.5-21.
