TP,
It is not an uncommon fault, especially when converting to a new type when one is focussed on flare characteristics for the first few landings - one concentrates on one hand and forgets the other.. but it is easily fixed with practice.
You serious, man?
To me it has always been "hands on throttle and stick", even forty years ago in a Piper Cub, since I always came in a bit low over the fence....
Translated, it always has been "power and attitude", if you see what I mean.
It sounds from what you say, that that link has been broken somewhere. Even if you have A/T until touchdown, some part of your awareness should keep track of what the "power" is doing.
