First outdoor grow: trying to figure out why I have pink/purple pistols

[OutDoorGrow16]

So I have couple plants growing outdoors an I was just curious if anyone here has ever seen or knows why the pistols on some of the buds are turning pink/purple an why some of the stems have turned purple

it happens all the time. genetics, ph, temperature, soil conditions etc

The ph is roughly around 6.8.. but yea I was also told temps play a big part in that so I was curious what people around here think

looks heavy N

Yup I recently had a bit of nitrogen toxicity error on my part my first grow an didn't know N was no good during the flowering stage.. so I decreased the N an upped the P&K using ionic boost an big bud advanced nutriant

It looks like a genetic thing, I've grown a few pink ones. Most were quite nice. Temps and media usually effect the leaves as well.
