I repotted my maple around the start of spring and reduced roots (quite a bit, say to 50%), but not the foliage. I have recently noticed a yellowing of the trunk, and the leaves have distinctly darker green veins on a lot of the leaves. Is this Chlorosis? or simply stress on the roots?

I also changed soil from mostly organic (from the nursery it came in) to about 40% perlite, and 60% potting soil.

I also moved it out into a position where it gets full morning sun. It was previously on a veranda.

Thanks everyone. It was just looking less green than my other JP.

@penumbra the other trunk is turning a golden-brown. Is this turning to bark then too?

The yellowing seems to be in the area where the green tissue transitions into brown bark. This could just be the tissue transitioning into bark.

More than likely. It is a common scenario for people with young maples.
Still good to ask, better safe than sorry.
