Deficiency of Potassium
There is probably a deficiency of Potassium (mobile). Chlorosis of the older foliage is initially interveinal for many Potassium deficient plants. As the deficiency becomes more severe, chlorosis extends to new growth and interveinal speckling or browning and marginal yellowing and leaf scorch develops. Irregular dead spots on the leaves may occur.
