The red / Blue scenario you're describing might explain why veg seems to have worked better than flowering.

I'm not so sure on the plants flexibility on wavelength. While I would subscribe to there being some deviation from lab to field, or also subscribe to some higher plants requiring slightly different coctails, It seems that if they don't get what they want they just don't do as well.

But who knows, is your very good point.
