Specific nutrient schedules for autoflowering cannabis

## Basics of autoflower nutrients

Autoflowering cannabis plants have a unique life cycle that differs significantly from photoperiod strains. They flower independently of light duration, which means that their nutrient schedules need to be carefully adjusted to optimally support the entire life cycle.

### Nutrient requirements in the seedling phase

In the seedling phase, autoflowers require only minimal nutrients. Too high an EC value can damage the sensitive young roots. Use a weak nutrient solution with an EC value of 0.4 to 0.6 mS/cm. The pH value should be between 6.0 and 6.5 to ensure optimum nutrient uptake.

### Vegetative nutrient supply

In the vegetative phase, autoflowers require a nitrogen-rich diet to promote leaf and root growth. An NPK ratio of 3-1-2 is optimal. The EC value should be gradually increased to 1.0 to 1.4 mS/cm. Be sure to monitor the plants regularly to avoid signs of over-fertilization.

### Flowering fertilizer for autoflowers

As soon as the autoflowers enter the flowering phase, the nutrient ratio should be adjusted to increase phosphorus and potassium. An NPK ratio of 1-3-2 is ideal for the flowering phase. The EC value can be increased to 1.4 to 1.8 mS/cm. The pH value should continue to be kept in the range of 6.0 to 6.5.

### Important considerations

Autoflowering plants have a shorter life cycle, which means that errors in nutrient supply have less time to be corrected. It is important to regularly measure and adjust pH and EC levels to achieve the best results. Be careful to avoid over-fertilizing as this can lead to nutrient lockout.

### Final considerations

Autoflowering cannabis can be an excellent choice for growers who want a quick harvest. Proper nutrient supply is crucial to realizing the full potential of these plants. By taking into account the specific needs at each stage of growth, you can grow healthy and high-yielding plants.

## Pro Tips

- Carry out regular pH and EC measurements.

- Avoid sudden changes in nutrients.

- Monitor plants for signs of deficiencies or over-fertilization.

- Use adapted autoflower fertilizers.

- Remember that less is often more to avoid over-fertilization.
