Sanbokan Lemon Tree Leaf discoloration?

Hi,
I have some leaf discoloration that I'd like help diagnosing. My tree is a sanbokan lemon or sweet lemon that is about 3-4 years old. It has tons of new growth but hasn't flowered in the last three years. I live in Montreal, Canada, so the tree is potted. It lives on a very sunny deck all summer and comes in to a not-as-sunny window in the winter. many of the leaves have yellow discolorations on them. I fertilize irregularly with espoma citrus tone. I know the most likely diagnosis is nutritional deficiency, but I read about HLB and I just want to be sure that isn't what I have.
Also, my plant is quite leggy. Not sure if that is relevant.

Any help would be greatly appreciated!
