obviously pends if the plant was grown above or below water in the first place. I still believe a sudden change of inviroment be it emersed or submersed, can cause such a noticeable effect on existing leaf growth.

it's not that easy with this plant, it's that delicate pruning old leaves could do more harm.
i found with this variety, it NEEDS co2 and do not starve of nutrients. i got next to nothing growth until i increased those 2
this was about a week in, from the emerged to emerged state. like Clive says, i don't find stems suffer from the emerged to immersed transition.
it's not the quickest of growers even with good conditions IME. but is very needy. you can see from the last image the pearling suggesting the higher amounts of co2...i really did pump it in border line stuff 8)
you can also notice the old leaves have nearly all but gone, and the beautiful needle type leaves twinkle almost. it read a description once that it was like a Christmas tree.
unfortunately the tank was pulled apart not long after this image, so i don't know the final out come.
in answer to your question, i'm with clive. co2 and in my case more ferts and one more bulb.
