You’re growing cannabis in coco? Then it’s time to master coco nutrients for cannabis.Coco coir has virtually no nutrients at all, and your cannabis plant will rely solely on the nutrients that you provide. In my experience, this is the step that will take your cannabis plant to new heights or cause it to fail. Of course, one of the biggest advantages is that once you understand how to feed your cannabis plant in coco coir, this is one of the most powerful methods of growing cannabis.
Why Coco Nutrients for Cannabis Are Different
Coco coir is a hydroponic medium. That’s a big word that means:
- Nutrients are taken up quickly by your cannabis plant
- Your cannabis plant grows fast
- You control all aspects of your cannabis plant’s growth
However, it also means:
- There are virtually no nutrients in coco coir
- Feeding your cannabis plant incorrectly will become painfully obvious
Which is why mastering coco nutrients for cannabis is so critical.
Essential Nutrients in Coco Growing
Your cannabis plant will need a balanced diet of nutrients. Here are the basic nutrients that your cannabis plant will need:
Macronutrients
- Nitrogen (N) – for leaves
- Phosphorus (P) – for roots and flowers
- Potassium (K) – for general health
Secondary Nutrients
- Calcium
- Magnesium
👉 Coco has the ability to bind calcium and magnesium. This is the reason CalMag is a requirement in almost all cases.
Micronutrients
- Iron
- Zinc
- Copper
Step-by-Step Feeding Strategy
Step 1: Start Light
Seedlings require less nutrients. Overfeeding in the beginning can hinder the growth of the seedlings.
Step 2: Use Coco-Specific Nutrients
Nutrients for coco are a requirement. Don’t use any other nutrient for coco.
Step 3: Maintain Correct pH
pH levels should be between 5.8 and 6.2 for optimal nutrient uptake.
Step 4: Feed Frequently
In the case of coco, the following feeding strategies can be implemented:
- Daily feeding
- Twice a day (advanced)
Step 5: Always Water to Runoff
In the case of coco, 10-20% runoff is necessary to avoid the buildup of salts.
Step 6: Add CalMag
This is a requirement in the case of coco and is necessary to avoid nutrient deficiencies.
Step 7: Adjust Based on Plant Response
If the plants are healthy and thriving, then the nutrient levels are correct. Always monitor the leaves and the overall health of the plants.

Coco Feeding Chart
| Stage | EC | pH | Feeding |
|---|---|---|---|
| Seedling | 0.5–0.8 | 5.8–6.0 | Once daily |
| Vegetative | 1.0–1.4 | 5.8–6.2 | 1–2 times daily |
| Flowering | 1.4–1.8 | 5.8–6.2 | 1–2 times daily |
💡 Tip: Always monitor plant reaction.
Common Coco Nutrient Mistakes
In the case of coco nutrient feeding of cannabis plants, the following common mistakes should be avoided:
- Overfeeding
- Skipping CalMag
- Incorrect pH
- No runoff
- Inconsistent feeding
Final Thoughts
One of the fastest ways to take your grow results to the next level is by mastering coco nutrients for cannabis.
