Mills Organics Feed Chart – Base, Grow and Bloom

Mills Nutrients' own published Organics schedule. Week by week, in millilitres per litre.

Organics is a separate line from the Mills bottles most people know. It is its own set of products — Base, Grow, Cal and Bloom — and it has its own schedule, three grow weeks and eight flower weeks. If your bottles say Basis A and Basis B instead, you want the mineral charts: High Concentrate on tap water or High Concentrate on osmosis water.

Mills Organics feed chart – millilitres per litre of Base, Grow, Cal and Bloom by week
  • All dosesper 1 litre
  • pHnone printed on this chart
  • Base feed0.5–8ml of Base

The week number starts again at 1 when flowering begins, so Grow 3 comes immediately before Flower 1.

Every figure is millilitres per one litre of water, not per ten. A 10-litre watering can needs ten times these numbers, so 8ml of Base becomes 80ml.

Getting it right

  • Read the dose as per litre. Most brands print per 10 litres, Mills print per litre. Multiply by the size of your can before you pour anything.
  • Grow is three weeks here, not two. The mineral Mills charts run a two-week grow phase; this one runs three. Do not carry the week numbers across from one chart to the other.
  • Bloom starts before the lights flip. The Bloom bottle comes in at Grow 3, at the same 2ml it holds for the rest of the run. It is the one figure on the chart that never changes.
  • Grow stops when Bloom starts. The two never overlap — Grow runs at 2ml for the first two weeks and is finished after that.
  • Base is the one that ramps. It climbs from 0.5ml to a peak of 8ml in Flower 5 and 6, then comes back down to 5ml for the last fortnight. Everything else stays flat or nearly so.
  • Mills print no pH or EC target on this chart. They give both on their mineral charts and neither here, so there is no published figure to quote. Do not borrow the mineral numbers.
  • Shake the bottles. Organic feeds settle. What is left standing at the bottom is the part you are paying for.

Common questions

Do you stock the Mills Organics bottles?

Not at the moment. We carry the mineral Mills line — Basis A&B, Start-R, C4, Ultimate PK and Vitalize — which you can see in the Mills range. The chart above is here because it is Mills' own published schedule and it is hard to find in one piece.

Is this the same as the Basis A&B chart?

No. Different bottles, different figures, different phase lengths. The mineral line runs two grow weeks and nine flower weeks and is split again by whether you use tap or filtered water. Start with the High Concentrate tap-water chart if that is what you have.

Why is there no pH figure?

Because Mills do not print one on the Organics chart. They publish a pH band on their mineral schedules but not on this one, so anything quoted here would be made up.

What if my bloom runs longer than eight weeks?

Hold the last printed week rather than inventing extra rows — that is 5ml of Base, 1.5ml of Cal and 2ml of Bloom — until you are ready to finish.
