Nutrients and deficiencies

Many growers will face problems with nutrient deficiencies. When this happens, your plant will suffer and tell you that something is wrong. Cannabis plants do this by changing the colours of their leaves.

Every type of nutrient deficiency will have their own characteristics in the colouring of the leaves which makes them pretty easy to spot (if you know what to look for). To help you with this, we have listed up all deficiencies and how they can be recognised. First of all we seperate different 2 types of deficiencies:

Mobile nutrients

(Deficiency symptoms that start at the bottom with lower, older leaves)
  • Nitrogen
  • Phosphorus
  • Potassium
  • Calcium
  • Magnesium

Immobile nutrients

(Deficiency syptoms start at the top with new growth)
  • Zinc
  • Manganese
  • Iron
  • Sulfur
