For a single plant, if kept short, you would've been okay with just the CFL and LED panel.

Bigsby - 680nm is too deep of a red and is not as efficient as 660 or 670. Also you really don't want white diodes unless you're absolutely sure the diode is peaking in the wavelengths you want - most white diodes are a blue or UV diode with a phosphor on them. They're pretty inefficient as-is and won't last as long as a true single-color diode.
