Leaf Discoloration [Orange tree]

[JoeR]

Afternoon B-nut,

I have a large Calamondin orange tree that is not exactly a bonsai but it is in a large pot with bonsai soil. I have noticed some discoloration on the newer leaves; some of them are slightly yellow in the center but green towards the edges. I think it may be too much sun or the result of unconsistant fertilizing. I dont think I fertilize it, or any of my trees really, enough.


Any ideas what the issue is?


Thanks im advance for help.
Joe

Are the new leaves hardened off yet? It's hard to tell from this photo. Here's a graphic that may be helpful.
