Citrus - Chlorosis
Symptoms
Magnesium deficiency causes interveinal yellowing on older leaves first.
Discoloration intensifies on leaf tips and leaf margin. These areas become completely yellow, veins included.
Then chlorosis proceeds towards the petiole attachment point.
Leaf base remains green for the longest time.
At prolonged deficiency younger leaves are affected too.
Reasons
Magnesium deficiency on leaves of lemon

Magnesium deficiency on lemon made worse by
- Sandy soils
- Acidic soils
- Potassium rich soils
- Soils receiving high potash applications
- Cold wet periods
Magnesium is important for
- Combats chlorosis
- Prevents premature leaf fall
- Gives healthier greener trees
