Organic cannabis nutrients

Why nutrients matter when growing cannabis

Great genetics set the foundation. Proper cannabis nutrition allows your plants to fully express their genetic potential. From early root development through to late flowering, cannabis plants require a balanced supply of macro and micronutrients to grow strong, healthy and productive.

• Strong root systems
  
  
• Healthy leaf and stem growth
  
  
• Efficient photosynthesis
  
  
• Dense, resinous flowers
  
  
• Enhanced cannabinoid and terpene production
  
  
• Consistent yields

Poor nutrition can limit even the best cannabis seeds. With the right organic inputs, plants grow steadily, remain resilient and produce high quality buds with excellent aroma and flavour.

At Dutch Passion we focus on breeding exceptional genetics. For plant nutrition, we partner with specialist brands that have decades of experience and proven results.

Our recommended organic nutrient partners

We work with two highly respected names in organic cannabis nutrition: BioTabs and Terra Aquatica.

BioTabs

BioTabs specialise in slow-release organic tablets and beneficial microbes that create a thriving living soil ecosystem. Many growers appreciate the simplicity of the water-only approach once the system is established.

Best suited for:

• Soil grows
• Coco grows
• Growers who prefer a low-maintenance feeding style

Terra Aquatica

Terra Aquatica produce fully water-soluble organic dry powders suitable for soil, coco and hydroponic systems. Their one-part veg and bloom powders are easy to use and cost-effective.

Best suited for:

• Soil, coco and hydro
  
  
• Growers who want precision with organic inputs
  
  
• Vegan friendly nutrient programmes

Both brands are chosen for reliability, ease of use and consistent performance alongside Dutch Passion cannabis genetics.

What nutrients do cannabis plants need?

Cannabis plants rely on three primary macronutrients:

• Nitrogen (N) for vegetative growth.
  
  
• Phosphorus (P) for root development and flowering.
  
  
• Potassium (K) for overall plant strength and flower formation.

They also require secondary nutrients such as calcium, magnesium and sulphur, plus trace elements including iron, zinc and manganese.

A balanced feeding schedule ensures steady growth during the vegetative stage and strong bud production during flowering.

Organic nutrients vs synthetic fertilisers

Cannabis plants ultimately absorb the same mineral elements, whether they originate from organic cannabis nutrients or synthetic fertilisers. The key difference lies in how nutrients are delivered, how they interact with the growing medium, and how they influence long-term plant health and soil biology.

Synthetic fertilisers are manufactured mineral salts designed for immediate availability. They allow precise control and rapid uptake, which can produce fast growth in tightly managed environments. However, they do not contribute to soil biology and can lead to salt build-up if overused.

Organic nutrients, by contrast, are derived from natural plant or biological sources. Instead of feeding the plant directly with isolated salts, they feed the soil ecosystem. Microbial life breaks down organic inputs into plant-available forms, creating a more natural nutrient cycle.

This living soil approach offers several advantages:

• Supports beneficial microbial activity
  
  
• Improves soil structure over time
  
  
• Encourages steady, balanced growth
  
  
• Reduces the risk of sudden overfeeding
  
  
• Often enhances aroma and flavour expression

At Dutch Passion, we believe exceptional genetics deserve a natural feeding strategy. That is why our recommended nutrient partners follow an organic philosophy.

Whether you choose slow-release living soil systems or fully water-soluble organic powders, our approach remains consistent: clean, organic inputs that support plant health from root to harvest.

While mineral systems can be effective in skilled hands, our stance is clear. We support organic cultivation methods that work in harmony with the plant and its environment.

Cannabis nutrients by growth stage

Cannabis plants require different nutrient ratios during seedling, vegetative and flowering stages. Choosing the correct cannabis fertiliser for each phase supports steady growth and maximises final results.

Root / starter nutrients

These gentle, root-focused formulas are highly diluted and provide essential nutrients to encourage strong early root development in seedlings and clones. Low nutrient concentrations help young plants establish quickly and absorb nutrients efficiently without overwhelming (‘burning’) their delicate roots. 

Vegetative stage growth nutrients

High-nitrogen formulations promote vigorous leaf, stem and branch growth during the veg phase. This builds a robust structure and canopy for better light capture and future bud sites during subsequent bloom.

Flowering stage growth nutrients

Low-Nitrogen, high-Phosphorus and high-Potassium formulas support bud formation, resin production, and flower density in the bloom phase. This all drives bigger, denser buds with enhanced terpenes and cannabinoids

Additives and boosters

Specialised supplements like PK boosters, root stimulators and bloom enhancers fine-tune nutrition beyond base feeds. These tend to be used by more experienced growers chasing improved terpene profiles, sweeter flavours and/or maximum yield.

If this all sounds complicated, keep it simple. A well-designed base organic nutrient from BioTabs or Terra Aquatica will deliver excellent results with minimal adjustment.

Cannabis nutrients by grow medium

Different growing media influence how cannabis nutrients are absorbed and managed. Choosing the right fertiliser for soil, coco or hydroponics ensures balanced feeding and healthy plant development.

Soil nutrients

Soil naturally buffers pH and contains microbial life. Organic soil nutrients work with this ecosystem to release nutrients gradually, supporting healthy growth and rich flavour development.

Slow-release tablets and organic dry powders are popular choices for soil growers who want a forgiving and stable system.

Coco nutrients

Coco is inert and drains quickly, meaning all nutrition must be supplied through feeding. Coco-specific formulas often include additional calcium and magnesium to prevent common deficiencies.

This medium offers fast growth and strong root development when managed correctly.

Hydroponic nutrients

Hydro systems rely entirely on soluble nutrients delivered directly to the roots. Precision is essential, as pH and EC levels must be monitored carefully.

Water-soluble organic powders such as Terra Aquatica Organic DryPart are suitable for hydro and bioponic setups.
