Nitrogen Deficiency

Description:

Lower leaves first appear pale green. The leaves then yellow and die as the Nitrogen travels to support new growth. Eventually, the deficiency travels up the plant until only the new growth is green, leaving the lowest leaves to yellow and wither. More common in veg as nitrogen is needed more early in the plant's life.
