Got Some Purple Stems

Hey there guys so I've got some plants that are growing healthy and strong. Only thing is there stems appear to be purple.. not the main stalk but the stems attaching the leaves to the main strong are purple. Just wondering if this is natural or is it because of Magnesium or Phosphorus deficiency ?

The strains in question are Skunk and Kush I got from bagseed.

Not a problem. Just genetics.

If there were a problem with nutes, look for it in the leaves. Only then would it matter if you also had unusually red stems compared to earlier in your grow. This is a non-issue, I'm happy to report.

Thats what I was thinking cuz there displaying strong healthy growth, usually when its from a nute def its causes stunted growth correct? I've read about this before, just looking for some insight from guys make me feel better haha

typically a sign of good health when there are no other signs of stress
