Jade, it's not a lack of vitamins, this problem is caused by one you probably cannot see. When citrus trees begin to drop green leaves the culprit is almost always found in the root zone. Either rot or a root pathogen is the cause. Without actually seeing it I can't go much further. Lemons do very well in large pots which may be an option for you. The sad thing is that your tree is probably already beyond saving. For the next one, make sure you have a very well drained hole you plant it in, and make sure the soil is free of pathogens.
