Canna Coco A & B – Complete Professional Nutrient for Coco Coir, Easy 2-Part Formula for Growth & Bloom

Canna Coco A & B is the definitive, professional-grade nutrient solution engineered exclusively for the unique demands of coco coir cultivation, delivering explosive vegetative growth and profuse, resinous flowering in one streamlined formula.

Struggling to dial in the perfect feed for your coco grow? You're not alone. Coco is a fantastic medium, but its specific cation exchange capacity and drainage properties can throw off standard nutrient schedules, leaving your plants hungry or locked out at the worst possible time. This frustration often leads to stunted growth, pale leaves, and underwhelming harvests that don't live up to the potential you know your genetics hold. It feels like you're constantly playing catch-up, guessing at EC and pH, never quite unlocking that legendary coco yield.

Forget the guesswork. Canna Coco A & B is your clear, phase-based path to mastering coco. Developed after years of research into substrate behavior and plant leaf analysis, this two-part system provides everything your plants need, precisely when they need it, from the first true leaves to the final flush.

Phase 1: Preparing Your Coco & Reservoir

Before you mix a single drop, setting up correctly is half the battle. Coco coir needs to be properly buffered and your environment dialed in to let Canna Coco A & B work its magic.

• Buffer Your Coco: Always start with a high-quality, pre-buffered coco like Coconut Substrate. If using unbuffered coco, rinse it thoroughly with a light nutrient solution at 0.4 EC and a pH of 5.8 before planting.
• Check Your Water Source: Know your starting EC and pH. RO or soft water is ideal. If using hard tap water, consider a Humidity controller with pH monitoring to stay on track.
• Clean Equipment: Use a clean, dedicated reservoir and mixing tools to prevent contamination.
• Environment Check: Ensure your Grow lights and Climate Control are set for the stage your plants are in (veg or bloom).

Phase 2: Mixing Canna Coco A & B Correctly

The "A&B" system exists for a crucial reason. Mixing them in the right order ensures every element remains available to your plants.

1. Fill Your Reservoir: Add the required amount of water to your tank.
2. Add Part A First: Shake the Canna Coco A bottle well. Add it to the water at a ratio of 4ml per liter (40ml per 10L). Stir vigorously.
3. Then Add Part B: Shake the Canna Coco B bottle. Add it at the same 4ml per liter ratio. Stir vigorously again. Never mix the A and B concentrates directly together—this will cause nutrient lockout.
4. Let it Stabilize: Allow the solution to sit for an hour, then check and adjust your pH to the sweet spot of 5.5 - 6.2 for coco.
5. Final EC Check: Your final solution EC (including your water's base EC) should typically land between 1.2 and 2.3 mS/cm².

Phase 3: The Feeding Schedule & Grow Cycle

With your nutrient solution mixed, it's time to feed. The beauty of Canna Coco A & B is its simplicity across the entire cycle.

1. Seedling/Early Veg: Start with a 1/4 strength solution (~1ml/L of each part). Water when the top inch of coco feels dry.
2. Full Vegetative Growth: Ramp up to full strength (4ml/L each). Your plants will show deep green, vigorous growth. Ensure strong Air Extraction for optimal transpiration.
3. Transition to Bloom: As you flip the lights, continue using the same Canna Coco A & B formula at full strength. The plant uses what it needs.
4. Peak Flowering: Maintain full-strength feeds. You'll see explosive bud development. This is when many growers add a bloom booster for extra weight.
5. Flushing: In the final 7-10 days, switch to plain, pH-adjusted water to cleanse the medium and improve final flavor.

Phase 4: Reservoir Maintenance & Troubleshooting

Keep your system clean and your data logged for consistent results harvest after harvest.

After each grow cycle, thoroughly clean your reservoir and irrigation lines to prevent salt buildup and pathogens. Always store your Canna Coco A & B bottles in a cool, dark place—UV light can degrade the premium iron chelates inside. Get into the habit of logging your EC and pH readings daily; this logbook will be your best friend for diagnosing any minor issues before they become problems. Notice tip burn? Slight overfeeding—dial back EC by 0.2. Seeing interveinal chlorosis? Check your pH first—it's usually a lockout, not a deficiency.

Advantages of This Coco-Specific System

Following the Canna Coco A & B method isn't just about following instructions; it's about unlocking coco's full potential with confidence.

• One Formula Simplicity: No switching between Vega and Flores bottles. Less confusion, fewer mistakes.
• Optimized for CEC: Formulated specifically for coco's cation exchange, preventing calcium and magnesium lockouts common with other nutrients.
• Instant Availability: The high-quality chelates and humic/fulvic acids make nutrients immediately absorbable, leading to faster response times.
• System Versatility: Works flawlessly in run-to-waste, drip systems, flood tables, and hand-watering setups.
• Predictable Results: Takes the mystery out of EC and pH in coco, giving you control and repeatable harvests.
• Healthier Root Zones: Promotes strong, white root growth by maintaining ideal ionic balance in the rhizosphere.

Frequently Asked Questions

Can I use Canna Coco A & B in soil?

It's not recommended. Canna Coco is specifically engineered for the drainage and cation exchange properties of coco coir. For soil, you'd want a dedicated product like Soil For Cannabis with a nutrient line designed for it.

Why two separate bottles (A & B)?

Certain elements in high concentrations can precipitate (form solids) when combined directly. Keeping them separate until diluted in water ensures every nutrient stays soluble and fully available to your plants.

My EC is too high/low. What should I do?

Always measure your water's base EC first. If your final mix is too high, dilute with fresh water. If it's too low, you can slightly increase the dosage, but never exceed 5ml/L per part. Consistency is more important than chasing a number.

Do I need additional Cal-Mag with Canna Coco?

Generally, no. Canna Coco A & B is fortified with the ideal calcium and magnesium ratios for coco. Adding extra can cause nutrient imbalances. Only supplement if you see a definitive deficiency and have ruled out pH issues.

How long can I store the mixed solution?

It's best used within 1-2 weeks. Keep it in a dark, cool reservoir with adequate aeration to prevent stagnation. Always check pH and EC before use if stored.

Personal Experience of Pevgrow’s CEO (Alan)

Let me be real with you: when I first switched to coco, I burned more than a few plants trying to use my old soil nutrients. It was a mess. Then I tried Canna Coco A & B, and it was like the clouds parted. The single-formula-for-veg-and-bloom thing seemed too good to be true, but it works. My process now is dead simple: I mix my reservoir every Sunday, always A then B, let it bubble for an hour, pH it to 5.8, and that's it for the week. The plants are consistently darker green, and the stretch during early flower is noticeably more vigorous compared to when I was winging it. The only tweak I make is during weeks 3-5 of flower, where I'll add a splash of a PK booster to really stack the buds. The biggest lesson? Trust the system. Don't overcomplicate it. Coco is hungry and drains fast, so consistent feeding with this stuff is key. My pro-tip: get a good PH meter and check your runoff EC occasionally. If the runoff EC is creeping more than 0.5 above what you're putting in, it's time for a light flush with plain, pH'd water before resuming normal feeds. It keeps everything in perfect balance.
