If it's chlorosis then yes it needs some nutrients. I have gotten the liquid iron (chelates iron) and sprayed mine when I had this problem. The reason I had it was my soil ph was too high which I had to correct. I had one potted plant that had it and it just needed a little TLC with some slow release fertilizer, alfalfa, and a little ironite and then fertilized with miracle grow.
Poplarcreek may be right about spider mites, but it really doesn't look like spider mite damage to me and I've had lots and lots of spider mite to contend with.
