Nitrogen Deficiency

We have 4 citrus bushes in our backyard and over the past few weeks I have noticed that one is going into decline. This weekend I was able to do a little research on the matter and I think I have come to the conclusion that my bush has a nitrogen deficiency. The UF extension office web site has wonderful advice on every kind of issue that a gardener could have in Florida. It is a great resource to use. I have officially diagnosed the problem with the Eureka Lemon as Yellow Vein Chlorosis. This also could be caused by water damage. To treat this problem, I will be monitoring the irrigation in the area and I have applied some cottonseed meal I had in the garage to increase the nitrogen levels a bit. Hopefully I will be able to save our only lemon bush.
