Purple stems ?

So my plants are doing pretty good for only being a little over a week old from seed. I noticed all 3 of my plants have purple stems. They all look very healthy. I did some searches didn't find any good answers and was wondering if you guys could tell me what it is from? Or if its something to be concerned about.
PH - 6.5
Temp - 77-81F


Thanks in advance!

Happy Growing.

Wouldn't worry about it,normal for seedlings. It should go away when they get bigger.

Being a newbie, it scared the living gunk outta' me when I first saw it. All the stories I read about cold weather killing the stems turning leaves purple then stems, but once the stems started to fill out and thicken, they changed to green and now they are dark green, almost brown, so I wouldn't worry. They'll grow out of it given proper care.
