Symptoms

  • Molybdenum deficiencies are rare, but have been observed in plants growing in peat. Initially, the green of the leaves fades, particularly between the veins.
  • Later, leaves can turn yellow and die.
  • In some cases, parts of mature leaves remain green at first, giving rise to a blotchy appearance.
  • Symptoms start first in lower leaves and spread upwards, the younger ones remaining green.
  • Growth might appear normal but flowers stay small.
