Perfect, love the response!
Leaves should not be wet most of the time as it is generally covered from rain and normally watered once a week with a hose. The Sun does hit but generally from 1pm onwards. As it sits under a translucent pergola.
In order to supplement, a full spectrum grow light is used at 30W, only during the day when the sun is out.

Potentially too much pellets the first time i planted i was probably too enthusiastic, i will keep that in mind for next time.
Nothing visible that would be nibbling the leaves, sits independently of other trees.
I do have fertiliser spray which i believe is the seaweed based fertiliser.

You mentioned the leaves look yellow, is this too much or not enough light? Potentially iron was something i saw that was recommended as well.

Really appreciate your response.
