Citrus Leaf Spotting/Blotching
As with leaf yellowing, any blotching or other irregularity in citrus leaf color needs to be checked. Pay particular attention to where the blotching occurs; note the symptoms and if in any doubt have tissues analysed.
Potassium
Manganese
Manganese deficiency is usually seen on young leaves as mottled yellowing of the leaf. The veins stay green while the interveinal areas are light green to yellow. In extreme cases white spots can also be found between veins. Take care as this can be confused with zinc deficiency.
Molybdenum
Zinc
First stage zinc deficiencies occur as chlorotic leaf spots - known as 'mottle leaf' and/or white interveinal areas with green veins. Take care as this can be confused with manganese deficiency.
