CANNA Coco Feed Chart
CANNA Coco is one bottle for the whole run, ramped up through veg and tapered at the end. The chart below is CANNA’s own schedule, with the target EC on every week. Underneath it, our free calculator fits it to your pot size, plant count and cycle length, and works out exactly how much you need to buy.
The CANNA Coco feed chart
Millilitres per litre of water. Veg here is four weeks and flower nine, which is the commonest UK cycle. If yours is longer or shorter, the calculator fits the same schedule to it rather than simply running out.
Swipe the chart sideways to see every week.
| Week | Coco | Rhizotonic | CANNAZYM | Boost Accelerator | PK 13/14 | Target EC |
|---|---|---|---|---|---|---|
| Veg week 1 | 2.5 | 2.0 | 2.5 | – | – | 1.1 |
| Veg week 2 | 2.5 | 2.0 | 2.5 | – | – | 1.1 |
| Veg week 3 | 3.0 | 2.0 | 2.5 | 2.0 | – | 1.3 |
| Veg week 4 | 3.0 | 2.0 | 2.5 | 2.0 | – | 1.3 |
| Flower week 1 | 3.5 | 0.5 | 2.5 | 2.0 | – | 1.6 |
| Flower week 2 | 3.5 | 0.5 | 2.5 | 2.0 | – | 1.6 |
| Flower week 3 | 3.5 | 0.5 | 2.5 | 2.0 | – | 1.6 |
| Flower week 4 | 3.5 | 0.5 | 2.5 | 2.0 | – | 1.6 |
| Flower week 5 | 3.5 | 0.5 | 2.5 | 2.0 | – | 1.6 |
| Flower week 6 | 3.5 | 0.5 | 2.5 | 2.0 | 1.5 | 1.8 |
| Flower week 7 | 2.5 | 0.5 | 2.5 | 2.0 | – | 1.2 |
| Flower week 8 | 2.5 | 0.5 | 2.5 | 2.0 | – | 1.2 |
| Flower week 9 (flush) | – | – | 2.5 | – | – | – |
Target pH 5.8 to 6.2. Rhizotonic drops to a maintenance rate once the plant is rooted and flowering. Cannazym carries on through the flush, which is the point of it.
The mistake almost everyone makes with CANNA Coco
The 40 ml per 10 litres on the bottle is the peak rate, not every week. CANNA Coco is a ramped schedule: it starts at 2.5 ml/L, builds to 3.5 ml/L through the middle of flower, and comes back down to 2.5 ml/L for the last two weeks before the flush.
Feed the bottle rate from week one and you are running roughly 40% over the chart on a plant that is not big enough to use it. That shows up as tip burn and a rising runoff EC long before it shows up as a bigger yield.
Mix to the EC, not to the millilitres
The doses above assume your water starts at zero. UK tap water usually sits between 0.3 and 0.5 EC before you add anything, and that counts towards the targets in the last column.
So on tap water you will reach the chart’s own EC with slightly less nutrient than it prints. Use the doses to get close and the meter to know. On RO, the printed figures are the ones to run.
What a full CANNA Coco run costs
For a common UK setup, nine plants in 3 gallon Quick Fill coco bags, four weeks of veg and nine of flower, the whole cycle comes to about £305 across 5 products, mixing roughly 1,500 litres of feed.
The single biggest line on that bill is CANNA Boost Accelerator at around £151, against £38 for the base feed itself. That is worth knowing before you order, because it is usually the additives rather than the base that decide what a run costs.
The calculator prices your actual grow rather than this example, and prices the other fifteen brands alongside it, so you can see what you are paying for.
Which CANNA line should I be on?
CANNA Coco is for coco, and it is one formulation the whole way through, which is what makes it simpler than most. Four products in the tank at the busiest week.
- CANNA Terra — Terra Vega through veg, Terra Flores through flower. Two bottles.
- CANNA Hydro — Run-to-waste line for inert media. Hydro Vega then Hydro Flores.
- CANNA Aqua — Recirculating line, A+B. Aqua Vega then Aqua Flores.
The calculator only ever lists the lines that suit the medium you pick, so you cannot accidentally run a soil chart in coco.
