Plants that have a lack or deficiency of nitrogen have performance problems and show chlorosis or yellow or light green coloration. They are more prone to pests and diseases. The lack of potassium in the soil also causes the leaves to appear yellowish or blue-green, with dark yellow edges. They are more susceptible to fungal attack. With lack of water, dry soil, the leaves are decayed and also show a yellow hue.
