There is probably a deficiency of NITROGEN (mobile).

Nitrogen-deficient plants typically exhibit a uniform loss of green color (chlorosis) beginning on older foliage and eventually encompassing the entire plant. The leaves may be thin and reduced in size. Eventually the entire plant becomes stunted and retains few leaves. Nitrogen deficiency is very common in containerized or recently transplanted plants, but is less common in well established plants.
