Chlorosis is the result of the interruption of the production of chlorophyll (which cause the green pigment) due to not enough nitrogen or phosphorus and magnesium.  Lily leaves turn yellow or light greenish yellow.  Often this problem here in Manitoba is caused by a deficiency of Iron.  One other cause may be not enough light over a long period of time.  This may show up in yellow growing tips, i.e. rapid growing under heavy overcast conditions.  Light, heat and a fertilizer boost should correct the problem.
