Your plants look fine very healthy. Purple stalks and stems can be perfectly normal or a sign but they look just fine. Can be genetics, cooler temps can do it.

Genetics doesn't start purpling during flower. It's the lack of magnesium that causes that. I have a plant that is doing the same thing. I foliage feed it Epsom salt for a few days and all new growth did now purple. As I stopped, new growth purpled. I don't have pics of it but you can view my grow journal in my signature. Best to start giving it some magnesium. but I don't think you REALLY HAVE TO unless it's REALLY looking fucked up and purple.

Genetics can be the cause of purple stems.. Phosphorus and Magnesium def can cause purple stems... it can also just be a genetic thing.

mixing in dolimitic lime is a popular method for supplying mag in the MJ world.

Those look fine. I wouldnt worry about deficiencies unless youre seeing signs of it in the leaves, and those leaves look lush and healthy

I watched a video about LED lights from a large grow. The plants were in flower. The grower was being interviewed and mentioned the slight purpling was a good sign of protection against disease.

I think yours qualifies, but extensive purpling is often a sign of deficiency
