It's a mineral deficiency, most likely of Nitrogen.  Feed it with a
nitrogenous manure like dynamic lifter (chook poo) or if you want to go the
chemical route (Lanes, Yates etc) citrus food.  Particularly with the
latter, which is very concentrated, don't overdo it or all the leaves will
fall off!  If you are in a cool area wait until the last likely frost before
you feed or you could encourage new soft growth that will be burned off by
the next frost.

Had a similar problem some 30 years ago
Situation :  WA, sandy white "soil"

A friend qualified in this area (ag science) advised me to apply a spray
of Molybdenum (sulphate??) to the leaves.  He supplied me with (from
memory ... molybdenum sulphate ???? ... 30 years ago .. sorry)
This had the desired effect.

Understand that there is a need to balance molybdenum and lime
Either robs the other (prevents the other from being effective)

In subsequent years, I have just dissolved mineral supplements and
sprayed on leaves.  Kept the yellow leaves at bay.

Yep, it could be a trace element deficiency.  There are quite a few things
that cause leaf yellowing, I suggest starting with common ones (citrus are
heavy feeders of nitrogen) and going on to rarer ones if it don't improve.

 Lime and chook manure has been my best friend when it  comes to oranges
and lemons.
Most soils tend to go acid and this helps fix it.
