I just can't work out what this is lacking. It had Epsom salts some time ago, then manganese. It has improved, but still missing something. Do you think it may need nitrogen?

I would check the symptoms for Iron, manganese and zinc deficiencies. It could be a rootstock problem, rootstock doesn't like pot mix , or pH problem, nutrients are out because pH not suitable for rootstock.
These two problems are linked.

You might try a seaweed or trace element foliar spray or liquid feed.

jakfruit, I checked for all those, and added them accordingly - or my son did, as instructed. The only element that has not been added is zinc, but this doesn't look at all like zinc deficiency in my experience.

It has been in a pot for many years (belonged to his dad), so not a rootstock problem. It had been neglected, but has improved and produced fruit with TLC from my son. This particular deficiency has defeated me - I can usually tell at a glance what might be missing.

Different Citrus rootstocks prefer certain soil conditions, some are better for alkaline soils, heavy soils, sandy soils etc etc. Maybe the pot mix has changed or leached over time, or pH changed ?
This might change nutrient availability.
Maybe a pH test ?
I wouldn't fully repot, maybe take out some of the top mix and refresh.
It looks a lot like a stage of Citrus Zinc deficiency from the pics i saw, but not the classic symptoms.
I'm not 100% sure on that, you may know more .

If its not Fe, Mn, Zn, maybe another of the lesser trace elements?

Thanks jakfruit. Next time I am at my son's house I'll take along my soil testing kit. I also suggested he send a pic or leaf to the Dept. of Ag's home gardening advisory service - if they still have it.
