Cocos A+B Plagron – Complete Mineral Nutrition for Coco Growers · Fast Absorption & Balanced Formula

Cocos A+B Plagron is the complete mineral nutrition solution for growers using coconut-based substrates, delivering fast absorption, balanced feeding, and explosive growth from the first week of your cycle.

Worried your plants aren’t getting the right nutrients in coco? You’re not alone. Many growers struggle with lockouts, deficiencies, or weak flowering because their base nutrients don’t account for coco’s unique chemistry. The wrong formula means poor uptake, wasted feed, and disappointing harvests — no matter how good your genetics are.

And if you ignore this mismatch? You’ll end up with yellowing leaves, stunted buds, and the frustrating feeling that you’re doing everything right but still getting mediocre results. It’s not your fault — it’s your fertilizer. Most one-part solutions can’t deliver the calcium and phosphorus plants need without causing precipitation. That’s why you keep chasing fixes with additives, pH swings, and guesswork.

The solution? Cocos A+B Plagron — a scientifically split formula that gives your plants everything they need in perfect balance. Because Cocos A delivers calcium and Cocos B brings phosphorus, they stay soluble when mixed with water, preventing nutrient bind-up and ensuring maximum availability. Developed specifically for buffered coco, this two-part system keeps your plants strong, healthy, and flowering hard — without the stress.

Why Cocos A+B Is the Smart Choice for Serious Coco Growers

This isn’t just another A&B — it’s a precision tool for maximizing your coco grow. Whether you're running a simple DWC setup or a full recirculating system, Cocos A+B adapts to your style. The new improved formula boosts early development, so you see greener, more vigorous plants within days. Plus, it’s forgiving across a wide pH range (5.5–6.5), giving you stability even when conditions aren’t perfect. With consistent results, minimal residue, and no funky smell, it’s the clean, reliable feed that lets your genetics shine.

Key Features and Benefits

• Two-part mineral formula prevents calcium-phosphorus lockout, ensuring full nutrient availability and strong root development.
• Faster nutrient uptake leads to visible improvements in plant vigor and color within the first week of use.
• Perfectly balanced for coco — meets the high water and nutrient demands of coconut substrates without salt buildup.
• Works across a wide pH range (5.5–6.5), reducing the need for constant adjustments and increasing system stability.
• Highly concentrated — a little goes a long way, making it cost-effective over multiple grows.
• Clean and odorless — ideal for discreet indoor grows and recirculating systems.
• Universal compatibility — works seamlessly with drip irrigation, DWC, ebb & flow, and hand watering.

Common Doubts — Clear Answers

Let’s clear the air on the usual concerns:

• You think that two-part nutrients are complicated. In reality, Cocos A+B is just as easy as any other — add 4ml of each per liter, every time you feed.
• You think that mineral feeds burn roots. In reality, this formula is gentle and stable, especially when used with proper runoff.
• You think that coco needs organic-only inputs. In reality, mineral nutrients like Cocos A+B offer precise control and faster results, especially in fast autos.
• You think that pH swings will ruin your run. In reality, this system buffers well and performs reliably even with minor fluctuations.

How to Use Cocos A+B Safely and Effectively

Using Cocos A+B is simple, but following best practices ensures top performance and long-term success.

1. Shake both bottles well before each use to ensure even distribution of nutrients.
2. Add 4ml of Cocos A per liter of water, then mix thoroughly before adding 4ml of Cocos B.
3. Always dose A and B separately — never mix them in concentrated form to avoid precipitation.
4. Use the solution with every watering to maintain consistent nutrient availability.
5. Monitor pH after mixing and adjust to 5.5–6.5 if needed, especially in 100% coco setups.
6. Check EC regularly and ensure proper runoff (10–20%) to prevent salt accumulation.
7. Store unused solution for up to 10 days in a clean, dark container — avoid mixing with organic additives.

Frequently Asked Questions

Can I use Cocos A+B in hydroponics?

Yes, absolutely. Cocos A+B works perfectly in hydroponic systems like DWC, ebb & flow, and NFT when used with inert media such as coco coir or rockwool.

How long does a bottle last?

A 1L bottle of each can last 2–4 grows for small to medium setups (e.g., 4–6 plants). Due to high concentration and low dosing, it’s extremely economical over time.

Do I need additives with Cocos A+B?

Not necessarily. Cocos A+B covers all base nutrients. However, you can boost results with Plagron additives like Green Sensation or Sugar Royal during flowering for even bigger yields.

Is it suitable for autoflowers?

Yes. Many growers successfully use Cocos A+B for autoflowering strains. Just follow a reduced feeding schedule — start at half dose and increase gradually.

Can I mix it with other nutrient brands?

We recommend using it as a standalone base. Mixing with other mineral lines can cause imbalances or precipitation. Stick to the Plagron ecosystem for best results.

Personal Experience of Pevgrow’s CEO (Alan)

I’ll admit — I was skeptical at first. Two bottles? More work? But after seeing friends get cleaner grows and better results with Cocos A+B, I gave it a shot. Now, it’s my go-to for any coco run. I used it on a recent Auto Somango grow — 6 plants in 11L pots — and the difference was obvious by week three: darker green, thicker stems, and zero deficiencies. I dose 3.5ml/L in veg and bump to 4ml in flower, always with runoff. No pH drama, no residue, and the yield was dense and fragrant. The best part? I didn’t have to babysit the reservoir. It just worked. If you’re serious about coco, this is the foundation you need.
