Can HC leaves shrink?

I have been trying to grow HC in my tank with limited success. I seem to have periods of decent growth, followed by what looks like the HC leaves actually shrinking. I can see a distinct size difference between new leaves and older, much smaller leaves.

Is there a specific deficiency that would cause this?

I'm using EI dosing, and don't have problems with any other plants in my tank.

That's CO2.

When there's plenty of CO2, leaves get larger.
