Yellow leaves on unidentified tree

Back in January, I posted a thread trying to identify this little tree
https://forum.gardenersworld.com/discussion/1070288/is-this-a-citrus#latest
Fast forward and we now have a very unhappy plant. It got what I think was a mite infestation at the end of winter. Working on that assumption, it has been sprayed, lived outside through rain and lower temperatures since Spring, fed and watered but not too much. It spent what passed as summer (not exactly a sunny one) on a south facing wall, then the last few weeks in an unheated, south facing greenhouse.
As you can see, it has grown well but is more and more yellow. Many of the leaves have brown/black specks but when I mist it I'm no longer seeing any spider like web, which I did before.
I brought it in yesterday as temperatures are set to hit -5°C tomorrow night. My intention is to return it to the greenhouse when it's not too cold as we don't really have a spot in the house where it could get much light.
Photos:
And in case it helps identify it, it had a go at a flower but got no further than a bud.
Any thoughts gratefully received.

If you have some Epsom salts, try giving it a solution of those - 15ml of salts in 5 litres of rain water or distilled water if your tap water is at all alkaline. This will boost magnesium. You can also give it a drink of sequestered iron diluted according to instructions.
There are specialist citrus feeds containg higher levels of Potassium (P) and Phosphorus (K) which help with plant health, flowering and fruiting as well as Nirtogen (N) for healthy foliage plus other micro and macro nutrients for healthy citrus plants. You need to feed these from late September to April and then switch to one higher in Nitrogen for the summer.
And from now on it's an indoor/greenhouse plant. I have to believe the low light, poor temperatures and persistent winds this year didn't do it any favours.
Thanks again
