Shogun Coco Feed Chart – Samurai Coco A&B Doses
Shogun's own published Samurai Coco schedule. Week by week from cuttings through to the final week, in millilitres per 10 litres of water.
- All dosesper 10 litres
- pH5.5 – 6.5
- Base feed10–20ml rising to 30–40ml
How the weeks are numbered
Week numbers restart when flowering begins. The chart opens with your cuttings, counts the vegetative weeks up as Grow 1 to Grow 4, then starts again at Flower 1 on the day you switch the lights. Shogun print the vegetative period as a countdown on their own chart — the doses are identical, only the labelling is clearer here.
Every figure is millilitres per 10 litres. Geisha Foliar is a spray on alternating weeks from Grow 1, and Sumo Boost Foliar is a separate 2ml per litre spray in flower weeks 1 and 3 — neither goes in the tank. Conductivity is the nutrients only; add your own tap water reading on top.
Getting it right
- Never premix the concentrates. Each bottle goes into the water on its own.
- Silicon goes in first, and separately. Pre-mix it in 5 litres and pH that to about 6.5 before it joins the tank.
- Katana Roots drops from 50ml to 2ml once the cuttings are away — that first figure is a soak rate, not a feed rate.
- PK Warrior means cutting the base. Drop the Samurai Coco by 25 to 50% while it runs, and stop it before Dragon Force starts.
- The two foliar sprays never go in the reservoir. Sumo Boost Foliar is 2ml per litre, sprayed.
- pH drifts both ways. It rises through veg and early flower, then falls in the second half.

Common questions
How are the weeks numbered?
The vegetative weeks count up from your cuttings as Grow 1 to Grow 4, then the numbering starts again at Flower 1 on the day you switch the lights. Shogun number the vegetative stage backwards on their own chart, so their week −6 is Cutting 1 here and their week −1 is Grow 4. If you veg for longer, repeat the Grow 1 and Grow 2 figures.
Growing in soil or hydro instead?
Shogun publish a separate chart for each. See the Samurai Terra soil chart and the Samurai Hydroponics chart.
What is target conductivity?
It is the EC of the nutrients and additives on their own, in the units Shogun print. Add your own tap water reading on top of it — the chart does not include it.
Do I cut the base feed when PK Warrior goes in?
Yes — drop the Samurai Coco by 25 to 50% while PK Warrior runs, then stop PK Warrior before Dragon Force starts.
