Camera doesn't do it justice, the red/purple is MUCH more vivid in color.

Is it cold where you're growing them?

And older leaves yellowing are the first noticeable signs of a nitrogen deficiency. The phosphorus deficiency page says this:
Stems and the leaves' undersides may turn reddish-purple, but this can also be a sign of a phosphorus deficiency.
It goes on to describe other qualities of the deficiency being more noticeable. As far as any other sources of the red, the book describes sulfur deficiencies to cause reddening of stems.
Stems, leaf stems (petioles), and main veins turn reddish-purple starting on the leaf's underside. NOTE: The reddening of the stems and the veins is not always well pronounced.

I can't speak for deficiencies, just normal healthy growth. I see it with some phenotypes, sometimes just in certain spots. I've also seen it above an injured branch but there's no way to know if it wouldn't have been that color anyway.
I think what I meant was that you don't need to worry about it one bit on a healthy plant, imho. If the plants deficient, it'll tell you in other ways, trust me.
EDIT - wow, really? maybe that's a soil / low light thing.(?) My girls show me N def with the new growth immediately.
