It was growing under 1 x 840 and 1 x 827 18W fluorescent tubes - a combination that I now favour over daylight (865) fluorescents. It gained the majority of its colouration under the fluorescents and then approximately one week ago I moved it under my 35W metal halide lamp.

They are just 2' linear fluorescent tubes. One is cool white (840) and the other warm white (827).I'm not sure what you mean by 1 x 840 and 1 x 827 18W fluorescent tubes.
