Some of the references that I have listed include descriptions of B. reducta's natural habitat which may be of some help in determining what is wrong with your plant. Hope you don't mind my passing it on to the list. Turning on loads of lights benefits nobody except the power company. Our CPs will not be helped by the massive waste of energy. More CO2 will be produced in electricity generation.
More useless light helps turn a beautiful dark, starry sky into an ugly orange glow.
Think about turning lights OFF, not on. I am extremely pleased with the plant. I agree with Jeff, if your N. bical. None of the N.bical. plants I have do well when allowed to get cool, below 60F., some do worse than others. My friends at the New York Botanical Gardens are in urgent need of some nice large VFT's for an exhibit.
