Herbi Coco ABC Auto Nutes

AUTO NUTES™ COCO ABC is a New Zealand developed 3-part dry nutrient kit optimised for coco and high-performance liquid feeding.
Designed for growers who want clean, soluble nutrition with strong calcium, magnesium, potassium and trace element support in coco-based substrates.
The kit contains separate Part A, Part B and Part C nutrients, allowing you to adjust feed strength through vegetative growth, early flower/fruit set and heavy fruiting.

Part A – NPK 6-19-42 Chelated Micronutrients Fe, Bo, Mo, Mn, Cu, Zn
Part B – Magnesium Sulphate
Part C – NPK 15-0-0 Calcium Nitrate Coco-optimised 3-part dry nutrient system

AUTO NUTES™ COCO ABC is designed for growers using coco coir, coco blends, run-to-waste systems and high-performance liquid feeding.

Coco has specific nutrient requirements. It can hold and exchange calcium, magnesium and potassium differently from soil or plain hydro systems. AUTO NUTES™ COCO ABC is built around a flexible A/B/C format so growers can maintain a strong nutrient balance while adjusting feed strength through the crop cycle.

The system is especially suitable for fruiting and flowering crops with high potassium demand. What is included?

AUTO NUTES™ COCO ABC contains three separate dry nutrient parts:

Part A – Coco Base Nutrient
A custom NPK and trace element blend containing potassium nitrate, monopotassium phosphate, potassium sulphate and Rexolin APN trace elements.

Part B – Magnesium Sulphate
Provides magnesium and sulphur.

Part C – Calcium Nitrate
Provides calcium and nitrate nitrogen.

Keeping the parts separate prevents unwanted reactions in concentrate and gives the grower more control over the final feed solution. Why use AUTO NUTES™ COCO ABC?

Optimised for coco and coco-based substrates

Dry A/B/C system — no paying for water

Highly concentrated and economical

Flexible feed strength through the crop cycle

Strong potassium support for fruiting and flowering crops

Includes calcium, magnesium and chelated trace elements

Suitable for hand watering, reservoirs and run-to-waste systems

Easy to scale from small grows to commercial use

Developed in New Zealand Designed for coco performance

AUTO NUTES™ COCO ABC is ideal for growers who want a clean, mineral-based feeding system for coco.

The A/B/C structure allows you to increase or reduce individual nutrient parts depending on stage, EC target and crop demand.

For example, during heavier fruiting or flowering, Part A can be increased to lift potassium levels, while keeping calcium and magnesium stable. Basic coco feeding guide

Use the following as a starting point. Always adjust based on your water source, crop, EC, pH, runoff and plant response. Vegetative / early growth

Per 10 L water:

Part A: 5.1–5.4 g

Part B: 3.0–3.2 g

Part C: 5.7–6.0 g

Target EC: approx. 1.8–2.0 mS/cm
Target pH: 5.5–5.9 Early flower / first fruit set

Per 10 L water:

Part A: 7.0 g

Part B: 3.5 g

Part C: 7.0 g

Target EC: approx. 2.1–2.4 mS/cm
Target pH: 5.5–6.0 Heavy fruit / heavy flower

Per 10 L water:

Part A: 7.7–8.1 g

Part B: 3.5 g

Part C: 7.0 g

Target EC: approx. 2.3–2.7 mS/cm
Target pH: 5.6–6.0 High-K late stage option

For crops with very high potassium demand:

Part A: 8.7 g per 10 L

Part B: 3.5 g per 10 L

Part C: 7.0 g per 10 L

This option increases potassium by lifting Part A while keeping Part B and Part C stable. Important mixing instructions

Always dissolve each part separately before adding to your reservoir.

Recommended order:

Fill reservoir with water.

Dissolve Part A separately and add to reservoir.

Dissolve Part B separately and add to reservoir.

Dissolve Part C separately and add last.

Mix thoroughly.

Check EC.

Check and adjust pH.

Feed plants and monitor runoff.

Do not mix dry parts together.
Do not combine calcium nitrate in concentrated form with phosphate- or sulphate-containing products. Recommended pH and EC DOUBL
