Use an iron supplement and put it diluted in a spray bottle and apply to the leaves several times a day for a few days. This will usually correct the problem if done soon enough. I usually have some plants affected by this every year and transplanting doesn't always solve the problem. My soil has a fairly high ph so I keep a close eye for chlorisis every year and every time I see signs of it I spray the leaves with an iron supplement. Once the leaves go from pale green to yellow it is harder to correct and once they turn white it is usually too late for those leaves but if the iron supplement is added the new leaves that come out are frequently normal.
