Any ideas as to what might be happening?

Some of the most internal leaves of my maple trees are turning bright yellow....as shown in the attached photo... The new growth looks fine in the attached photos but I find the yellowing leaves troubling....any ideas\thoughts will be appreciated?

they might not be getting enough light. Partial outer defoliation might help get more sunlight to interior shoots so they dont die

Looks to me like just a few weak leaves. I won't think anything of it....just remove them.

Its shedding its inner leaves as new leaves grow. It is completely normal for it to do so.

My Crab was doing it, and upon closer inspection, it had scale.

The regular first small leaves that fell about a week or so before went paler yellow.

The scale yellow was more gold like that.

Is there anything crabs don't get? Love them and have many small ones but wonder why I bother.

I think part of their charm is how ugly and nasty, downright ratty they can be, yet the flowers are still beautiful, and the birds still find refuge.

If a damn bird wants refuge, the least it could do is eat scale!

Certainly all suggestions were plausible, unfortunately scales are the culprit...
