It looks undernourished. What do you feed it and how often?

Plant it in the ground. It will do infinitely better with a lot nless work. My potted citrus look the same many times a year. That is why my citrus trees are in the ground.

I give it some Jobes citrus fertilizer, maybe once a month and that is it. Maybe having it on drip is not helping?

It's hard fertilizing with organic fert in pots. Is the NPK on the bag showing 3-5-5 like I am seeing on Amazon?

Jobes spikes is not the best way to fertilize a tree. The deficiency with the tree is manganese. Manganese deficiencies in citrus are very common this time of year.. It almost always shows up on the newly flushed leaves. You can foliar spray a manganese nitrate or a manganese sulfate solution and that will easily take care of it. Many people don't do anything, and as the flush cycle stops the tree most all of the time catches up with manganese.

Great advice everyone, thank you so much. And with regard to the Jobes, it is a 3-5-5, organic

I agree the deficiency is indeed Manganese. What trace minerals does the Jobes product contain, and in what form (Soluble or non-soluble).
