How the weeks are numbered
Shogun count backwards through the vegetative stage and forwards through flower. Week −6 is your cuttings going in; week 1 is the switch to flower.
| Week | Stage | Samurai Coco A&B | Katana Roots | Silicon | CalMag | Sumo Boost | PK Warrior | Dragon Force | Conductivity |

Every figure is millilitres per 10 litres. Geisha Foliar is a spray on alternating weeks from −4, 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
Why do the weeks start at minus six?
Shogun number the vegetative stage backwards so that week 1 is always the switch to flower. Week −6 is your cuttings going in. If you veg for longer, repeat the −4 to −3 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.
