It is phosphite-based, carrying 7.4% phosphate and 6.6% potassium with trace boron, copper, iron, manganese, molybdenum and zinc, and Mills built it to bulk, harden and ripen flowers and fruit in the last weeks before harvest. On the Mills chart it joins C4 at bloom week 5, runs alongside it for two weeks, then carries the crop alone to week 9 at 2 to 3.5ml per litre. It is a PK booster, not a full feed, so it goes on top of Basis A\u0026amp;B. Mills says not to run it alongside another PK booster.\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;
