Deficiency of Nitrogen
There is probably a deficiency of Nitrogen (mobile). Uniform loss of green leaf color on the older foliage (chlorotic) is one of the first symptoms of Nitrogen deficiency. In advanced stages, leaf color fades to almost ivory (often with pink or reddish cast) and the leaves become thick, brittle, reduced in size and fewer in number. Eventually, the entire plant is stunted, chlorotic, sparsely foliated, and growth slows dramatically.
