Cannabis requires both macronutrients (NPK: Nitrogen, Phosphorus, Potassium) and micronutrients (Calcium, Magnesium, etc.).
Here’s a basic feeding guide:
Stage Nutrients Needed
Seedling: Light Nitrogen (N)
Vegetative: High Nitrogen (N)
Flowering: Low Nitrogen, High Phosphorus (P) & Potassium (K)
Autoflowers often need a different feeding schedule due to their rapid growth. Here’s a nutrient plan designed specifically for them:
Week Stage Nutrient Schedule
Week 0 Germination Plain water
Week 1 Seedling Plain water
Week 2 Vegetating ⅛ strength vegetative nutrients
Week 3 Vegetating ¼ strength vegetative nutrients
Week 4 Vegetating ¼ to ½ strength vegetative nutrients
Week 5 Pre-flowering ¼ strength vegetative + ⅛ strength bloom
Week 6 Flowering ¼ strength bloom + ⅛ strength vegetative
Week 7 Flowering ¼ strength bloom nutrients
Week 8 Flowering ½ strength bloom nutrients
Week 9 Flowering ½ strength bloom nutrients
Week 10 Ripening ⅛ strength bloom nutrients
Week 11 Flushing Plain water
