The chart as text

Stage Coco Grow Coco Bloom FinalPart EC (mS)
First roots 0.5ml 0.5ml 0.3–0.6
First true leaves 1ml 1ml 0.8–1.2
Growing 2.5ml 1ml 1.3–1.8
Pre-flowering 3ml 2ml 1.8–2.0
Flowering 1.5ml 3ml 1.4–2.2
Ripening 5ml 1.4–2.6

Both bottles go in at every stage, in changing proportions — Terra Aquatica label them Coco Grow and Coco Bloom rather than A and B.

Getting it right

  • Both parts, every stage. This is not a grow-then-bloom switch: the ratio shifts, but neither bottle drops out until ripening.
  • Never premix the concentrates. Each part goes into the water separately.
  • Empty the reservoir every 10 to 14 days.
  • Ripening is FinalPart alone, at up to 5ml per litre, for about ten days.
  • DualPart Coco or TriPart in coco? Both work. DualPart is the simpler two-bottle route built for the medium; TriPart gives you finer control and covers hydro as well.

Common questions

Is DualPart Coco the same as Coco A and B?

It is the same idea — a two-part coco feed — but Terra Aquatica name the bottles Coco Grow and Coco Bloom, and the ratio between them changes through the run rather than staying equal.

Do I still need CalMag?

On RO or very soft water, yes. Coco holds and releases calcium in a way that catches people out, which is why the CalMag sits alongside almost every coco schedule.

Why are the doses per litre?

Because that is how Terra Aquatica publish them. Multiply by ten if you are used to a brand that doses per 10 litres.
