Why would M111 produce stunted trees?

I do apologize, as this might make a difference, i found in my records Pomme Gris is on G16, not G11. But thats a dwarf…

Honeycrisp was on G935 but it never grew above 4 ft and then died.

Here’s how we started. I thought we cut as low as 18-24 inches but probably between 2-3 ft after looking at my old pics.
