Atami B'Cuzz Soil Feed Chart – Nutrient A&B Doses
Atami's own published B'Cuzz Soil Nutrient A&B schedule for soil. Week by week, in millilitres per 100 litres of water.
- All dosesper 100 litres
- pH and EC5.5 – 5.8 · EC 1.0 – 2.2
- Base feed100-200ml rising to 250-300ml, each part
Every figure is millilitres per 100 litres of water, which is a reservoir rather than a watering can. Scale it to what you actually mix: 100 litres is ten 10-litre cans, so divide by ten for a 10-litre can and by twenty for a 5-litre one. The Flower 2 base feed of 250-300ml per 100 litres is 25-30ml in a 10-litre can, of each part.
Getting it right
- A and B go in separately, at the same rate. Nutrient A into the water, stir, then the same amount of Nutrient B. Poured together neat they react and the calcium falls out as a white sludge.
- These are the highest figures of Atami's three charts. Soil starts at 100-200ml and peaks at 250-300ml, where the coco chart peaks at 200-300ml and hydro starts as low as 75-100ml. Do not carry a dose across from one chart to another.
- Soil is a reserve, so it does not need feeding every time. The medium holds what you give it and releases it slowly. Plain water between feeds is normal in soil and stops salts stacking up in the pot.
- Let the pot get light before you water again. Weight is the honest test. Soil kept permanently wet has no air in it, and roots that cannot breathe stop feeding whatever the chart says.
- Bagged soil comes with its own food. Most peat mixes carry a few weeks of nutrition, so the bottom of the Grow 1 range — or nothing at all — is often right for a young plant in fresh soil.
- One pH and EC band covers all three Atami charts. Atami print pH 5.5 to 5.8 and EC 1.0 to 2.2 for soil, coco and hydro alike. Set the water before it goes in and check it in the can.
- Flowering starts at Flower 1 on this chart. Atami number their own schedule week 1 to week 10 straight through, so the switch is placed where Root Stimulator stops and Bloom Stimulator starts — their week 3. Root Stimulator runs Grow 1 to Grow 2, Growth Stimulator ends at Flower 4, Bloom Stimulator starts at Flower 1, and PK 13/14 runs Flower 3 to Flower 7.
- Flower 8 drops the PK. Base feed and Bloom Stimulator run to the end. There is no plain-water week printed, so finishing on plain water is a week of your own after this chart.

Common questions
Where is the Soil Nutrient A&B in the list above?
We do not stock the two-part B'Cuzz Soil Nutrition A&B at the moment, so we have not linked it. The soil base we do carry from the same range is B'Cuzz 1-Component, a one-part feed with its own dose printed on the bottle — it is a different product from the two-part base this chart is written around, so follow its label rather than the columns above.
What does 250-300ml actually mean in my watering can?
It is the dose for 100 litres. A 10-litre can takes 25 to 30ml, a 5-litre can 12.5 to 15ml. Measure each part separately and use the same amount of A as of B.
Which week does flowering start?
Atami's own schedule runs week 1 to week 10 with no line drawn between veg and flower. On this chart the switch is placed at their week 3, where Root Stimulator stops and Bloom Stimulator starts, and the flower weeks are numbered from there. Flower 3 is the biggest change on it: PK 13/14 comes in and Bloom Stimulator steps up.
The chart lists a Growth Stimulator — why is it not above?
We do not stock the B'Cuzz Growth Stimulator at the moment. Everything else on the chart that we carry is listed.
Growing in coco or in a hydro system instead?
Atami publish a separate chart for each, at different rates — see the B'Cuzz Coco feed chart and the B'Cuzz Hydro feed chart.
