Canna Coco A & B Feed Schedule
The feed chart below is for moderately clean tap water with a start EC of .3; some adjustment may be needed based on your water quality. The amounts shown are based on the needs of supporting four marijuana plants grown in a mix of Canna Coco fiber and 30% perlite in 5 gallon cloth plant containers. You can adjust the amount of water needed based on the size of your grow, but the amount of nutrients for each gallon remains consistent.
For coco grows you’ll need to supplement your nutrient solution with CalMag Plus or another Calcium and Magnesium supplement. Coco growers frequently run into Ca issues. Learn how to use CalMag plus.
Canna Coco A B Feed chart for growing seeds or rooting clones
The following Canna Coco feed schedule is for starting weed seeds or rooting clones. It’s a very light mix. Lightly wet the coco medium (too damp won’t encourage root growth). Ph should be 5.8 – 6.0. Use gentle lighting at 24 or 18 hours per day, and if cloning use a humidity dome to allow your young marijuana clones to take in water from the air until their roots form:
Canna Coco A B Feed chart for vegetative growth stage
The Canna Coco A B feeding chart below is for small plants that have grown roots and entered the vegetation stage.
After transplanting weed plants to a larger container water heavily and then let the coco nearly dry out before rewatering a few times to encourage root growth. Roots won’t grow unless they’re reaching to find water, so overwatering early on will prevent your roots from growing as strong which will impact yields later.
Water to 15-20% runoff to prevent nutrient salt buildup. Ph should be 5.8–6.0.
Lighting continues for 18 hours per day during this stage. Once roots are established stronger lights such as Metal Halide can be used. Mother plants will stay on this feeding schedule continuously.
The amount of time spent in vegetation will determine the final size, a common rule of thumb is to flip the lights to 12 hours when plants are half the final desired height. This is very important if you’re growing indoors and need to limit the height of the plants.
Canna Coco A B Feed chart for flowering growth stage
Use the Canna Coco feed chart below is used once you switch your lighting to 12 hours per day. Continue to water to 15-20% runoff to prevent nutrient salt buildup. The chart below is based on 5 gallons of water.
Watering frequency depends on plant size, environmental conditions such as humidity and heat, as well as the size of the containers used. For plants in 5 gallon containers, I typically water every other day during veg and once daily in flower. Ph should be 5.8–6.0.
The Canna feeding chart is based on an 8-week flowering strain. The length of flowering for your specific strain may vary between 6-14 weeks. Most Indica hubrids for indoor growing are 8-9. You’ll need to modify your feed schedule a bit if you’re growing a longer-running strain.
Pay attention to the look of the plants instead of just relying on the timeframes shown in parenthesis. Same thing with autoflowering strains which begin to flower without requiring the lights to be adjusted from 18 to 12 hours. It’s important to flush marijuana plants during the final 7-10 days of flower. That means stopping using Canna A&B or any other NPK nutrients. If you’re running the full Canna Coco line of nutrients you can continue using Canna Boost during flush with Ph’d water. Once your weed is ready you’re ready to cut, dry and cure. Learn more about trimming weed, drying it, and how to cure it. The Canna Coco feed schedule above will show you the right amounts of Canna Nutrients you should use.
