Could be the age of the lights.  I also use VHO Aqua Suns (190W over 55
gal) and had a similar thing happen about the same time.  The plant came
from a tank with less light and was growing tall, when it was moved to
the high light tank it became compact and robust but then changed back
to growing tall after about 10 months. I figured that the swords were
reaching for the light once the bulbs became less intense.  I'll be
changing the bulbs soon and will then see if they make a difference in
the way the sword plants grow.
