The Mills range
Mills — Dutch bio-mineral feeding
Mills sits between a fully mineral feed and an organic one — a bio-mineral approach designed for growers who feed heavily without running into the lockout that pure mineral salts can cause at high doses. It's a compact range compared to some brands here, five products rather than twenty, because Mills sticks to a tight core system rather than a bottle for every micro-problem.
Basis Nutrients A&B is the base feed, C4 Flower Enhancer and Ultimate PK cover mid to late flower, Vitalize is a stress and vitality tonic, and Start handles propagation and early veg. Growers who like Mills tend to run heavier doses than a typical mineral feed allows without seeing the tip-burn that usually comes with pushing EC that hard, which is the main reason it's popular with growers chasing maximum yield per plant rather than working within a tight budget.
Basis A&B through to Ultimate PK forms a complete four to five-bottle schedule if you want to run the full Mills system rather than mixing brands, and the range works across coco, hydro and soil without needing separate medium-specific formulas the way Canna or Shogun do.
