I follow the tried and tested Canna Coco advice from their site.
I use Buffer Agent ( Cal/Mag) plus Canna Coco A & B. Canna PK 13/14 (1 wk only at 6 wks before harvest date) and I find Advanced Nutrients Nirvana works nicely together.
3 wks prior to harvest, I completely flush for 30 minutes. Then no more feedings. Harvest once the plant has eaten up all nutrients from the leaves and they have yellowed or gone red, and the trichs are bursting almost between cloudy and amber. Only water occassinally. Try to harvest with a dry plant pot.

For veg I use Canna Buffer Agent
( Cal/Mag)
Advanced Nutrients Sensi Grow Coco A & B

Seedlings are started in Root Riots and fed with Bio Bizz Root Juice.

Hope this is some use.
Happy growing!

3 week flush seems like alot for coco. Is it possible you are essentially killing the plant too early? Just wondering if you could had developed a little more mass in that time frame had you kept feeding longer. Do you find a benefit to this longer flush? Just curious.

You can/should use a little throughout the grow. Also, the pH can be 6.0 throughout the grow too.

You can still use a drop of root stimulator, however it isn't really necessary. Phosphorus is the food the roots are made of, and root stimulators on their own are about stimulating root growth without feeding root growth.

I think the nutrient companies could save growers a lot of problems by just making their basic nutrients something like an NPK of 5-8-12. People would use much lower EC's, not need root stimulators, and get less insect pressure too.

On top of a water EC of 0.6 (R/O filtered, re-mineralized by putting magnesium lime/maerl in R/O filtered water, and mixing it 1:3 with more R/O filtered water):

Seedling: 0.2 EC of Canna Coco A+B, and 0.2 EC of Plagron Green Sensation 0-9-10.
Veg: 0.4 EC of Canna Coco A+B, and 0.2 EC of Plagron Green Sensation
Flower: 0.4 EC of Canna Coco A+B, 0.4 EC Plagron Green Sensation, extra magnesium
Ripening: Hammerhead 0-4-10

I use canna coco full line along with their coco coir and have killed it every run in oxy pots fill and drain. I use calmag throught the grow at half strength

I use tap and let it sit for a day before use. Some strains I use full strength calmag

Full dose cal mag every water or ? Which brand cal mag? What is your final ec? How much ppm is your tap water?

My plants would NOT look good with 0.2 to 0.4 EC of Canna coco base nutrient at any stage but early seedling and rooted cuttings.

Floranova can settle out creating a layer of sludge. This will cause nutrient issues. It is not always easy to notice until it throws the weight of the bottle off when shaking, long after it is effecting nutrient profile.

I fixed it by making a drill attachment. It is a thick nutrient with heavy residue. I keep mums long term on it and am switching to a cleaner solution, feeling that it clogs up the medium over time.

Yes every water. I use general hydro. Honestly I don't know what ppm my tap water is and I don't really measure ec. I can tell you that my ppm is usually hovering right around where canna recommends after adding all nutrients. I use canna a,b,cannazyme, rhizzotonic, ph, and boost. I have found that if I'm in a pinch I can skimp on the rhizzo when they are bigger as well as the cannazyme.
