Symptoms
A common symptom of potassium deficiency is orange spotting, starting with the development of pale yellow spots on the leaves. These turn orange at severe deficiency, and the spots form bright orange, light-transmitting lesions along the pinnae of older fronds.
Reasons
Potassium Deficiency
K deficiency is very common in sandy or peaty soils.
Symptoms
A common symptom of potassium deficiency is orange spotting, starting with the development of pale yellow spots on the leaves. These turn orange at severe deficiency, and the spots form bright orange, light-transmitting lesions along the pinnae of older fronds.
They coalesce later to bigger chlorotic areas. These symptoms are commonly called 'Confluent Orange Spotting'.

Reasons
Potassium Deficiency
K deficiency is very common in sandy or peaty soils.
Symptoms
Bright yellow to white stripes occur on the leaf blade. Leaf margins and main vein stay green.
Reasons
Potassium Deficiency (N/K imbalance)
White stripe disorder’ is probably caused by an imbalance involving boron, excess N and insufficient K.
