I am about to harvest in about a week or two. I have two to be harvested. Same strain(Blueberry), in fact they came from the same plant(seeds)! The stems have been different ever since the were seedlings! One purple, and one green. They both are doing just fine! I do believe I read somewhere that they turn purple when cold, but my two have never been more then a foot from each other there whole lives! So who's to know!i have the same thing happening to me right now the stem was pure purple but now its turning nice and red they told me it might be strain but i have two of the same plants and the other stem is pure green

How old is your plant ? because most/all plants when they are young have a red/purple stem, it should become green soon. Not sure how long should it take though, maybe a week ?My baby plant has a red stem, it used to be kinda purple, just in a small part, but what does that mean? thx?
There is nothing to worry about, many strains have purple to red stems or any combination inbetween. I have been reading many threads which attribute this to either cold, stress or a nute def., I tend to disagree with all the aforementioned reasons. Over the course of 40 plus years I have run into many many strains which are this color naturally. I am attaching a pic from last years grow which is purplish red and was since it sprouted, it was grown between the outside and the greenhouse where I kept it at night. This plant had no stress and it certainly didn't have any nute def, also wasn't cold at the time of this growing.My baby plant has a red stem, it used to be kinda purple, just in a small part, but what does that mean? thx?

what kind of soil are you using? it looks thick. also, not to be nitpicky but it looks a bit leggy, ya might want to lower your lights a bit or get more of the 6500k spectrum in there. at 4 weeks they should be much larger, which is why i'm inclined to think it's a low ph. mine are less than 3 weeks with 5 sets of leaves. oh and 2 plants in 1 pot is not a good idea, they'll fight for food and light.

I know red comes from iron. Don't know if that sheds some light on the subjectView attachment 1161174View attachment 1161175 see the red also starts from those leaves exactly
