Purple stock and leaf stems P issue or genetics?

I've seen this so many times before on indica plants, I lean towards genetics, regardless it has yet to have a negative impact on yeild or quality for me or anyone else I know who's encountered it

From this chart it says sulfur deficiency. I usually only get the purple in veg and fades away in flower.
