Symptoms
Leaf margins are chlorotic and then scorched. This spreads to the intercostal areas. The leaf becomes bright yellow with necrotic tints. The basal part of the leaf blade remains light green at the last.
Mature leaves are affected first. Symptoms worsen with increased deficiency and leaf age.
Reasons
Magnesium deficiency.
Deficient leaf blades contain less than 0.1 % magnesium on dry basis.
Potassium deficiency can cause similar symptoms.
Leaves with salt burn show similar symptoms.
Strawberries - Chlorosis

Strawberries - Chlorosis
Symptoms
Leaves show interveinal chlorosis with spotty necrosis on their margins and dark discolourations between the veins. Mature leaves are affected first. Symptoms worsen with increased deficiency and leaf age. Finally the oldest leaves turn completely brown while the young central leaves remain green.

Deficient leaf blades contain less than 0.1 % magnesium on dry basis.
Potassium deficiency can cause similar symptoms, but normally the basal part of the leaf is affected, too. Leaves with salt burn show similar symptoms.
