Why is the neutral drawing more than the hot leg?
Kino Flo ballasts are generally not power factor corrected. They will draw double the current on the neutral from what is being drawn on the two hot legs. On large installations it may be necessary to double your neutral run so as not to exceed your cable capacity. The Diva-Lite and ParaBeam series of fixtures are power factor corrected and do not need additional capacity on the neutral.
