Canna Coco Feed Chart: A & B, Additives and EC by Week
Greens Horticulture ·
This is the CANNA COCO feed chart week by week: how much CANNA COCO A and B to use, when each additive goes in, and the EC to aim for. It is CANNA's own schedule, set out so it reads on a phone.
CANNA COCO feeding schedule
CANNA gives every dose in ml per 10 litres of water, so divide by ten for ml per litre: 26-33 ml per 10 L is 2.6-3.3 ml per litre. EC is in mS/cm. EC water is what CANNA assumes your water starts at; EC total is the finished feed.

Notes from CANNA
- * Double CANNAZYM to 50 ml per 10 L if you are reusing the substrate.
- ** CANNABOOST can go up to 40 ml per 10 L through flowering for extra strength.
- For a longer growth phase, repeat the rooting period II doses (days 6-25). For a longer flowering phase, repeat the generative phase I doses (weeks 3-5).
- PK 13/14 goes in for one week, 3-4 weeks before harvest.
- The schedule is written for plants that flower or fruit, starting from a cutting or seedling about a week old. How long each phase lasts depends on the plant.
How to mix a CANNA COCO feed
- Fill your tank or watering can with the water first.
- Add COCO A and stir, then add COCO B and stir. Never mix A and B together neat: always dilute one before adding the other.
- Add the additives for that week, one at a time, stirring between each.
- Check the EC and the pH last, once everything is in. A pH pen or pH and EC meter takes the guesswork out.
What you need
- CANNA COCO A & B - the base feed, used from start to finish.
- CANNA Rhizotonic - root stimulator, heaviest in the first weeks.
- CANNAZYM - enzymes that break down old roots in the coco.
- CANNABOOST - flowering stimulator.
- CANNA PK 13/14 - one week of phosphorus and potassium mid-flower.
- CANNA Coco Professional Plus and the rest of our coco growing media.
Very soft tap water or reverse-osmosis water? Coco holds on to calcium and magnesium, and CANNA make CALMAG Agent to top them up. Ask us if you're not sure whether you need it.
