Mills Nutrients FAQ's
No. That is how the range is built. Basis A&B stays on from start to finish; Start-R, Vitalize, C4 and Ultimate PK do the stage work instead of swapping the base. You carry fewer bottles and you do not have a flip-day changeover, but you also have less direct say over the base ratio than a grow-plus-bloom pair would give you.
Start-R is the propagation and early-growth bottle — on while cuttings and seedlings are putting roots down, not as a standing feed for the whole cycle. Sizes are 500mL, 1L and 5L. An early root system is what later growth sits on, which is why most full ranges keep a product for this window.
Pour part A into the water, stir it in, then pour part B. Do not combine the two concentrates in the bottle or in a jug — the elements they keep apart will react and drop out as sludge. Two-part formulas exist for that reason: they can hold a stronger, more tightly balanced mix than one bottle could keep in solution.
In flower, and only for a set stretch of weeks — not as a bottle you leave in from week one to chop. Concentrated phosphorus and potassium feeds are written for a window, not a standing dose. Running Ultimate PK and C4 together at full strength for the entire bloom is how EC climbs too far and lockout starts.
Start with the 100mL Vitalize — that is the smallest bottle Mills sells here, and the cheapest way to see if the line suits the room. Add a 1L Basis A&B set and you have a working feed for a small tent without buying a range you have not run yet.
