Some strains/phenos have a lot of purple in the stems, it is not always a sign of a problem.
Blurple lights like yours can sometimes cause increased anthocyanins which can create pretty purple petioles, too. It is one downside of blurple led.
Sometimes it is a sign of light stress, especially under blurple in my opinion, keep an eye for other symptoms but don’t do anything drastic unless you see some other signs of a problem.

I am looking into building my own light. I been watching growmau5 but don't have a full grasp yet. My light isn't blurple or I didn't think it was. the other plants one from the same pack of seeds don't have any purple. This is the plant I had cal mag issues with in the start of its life. This is the very first time I have ever grown anything and I have already been told my light is shit but it seems every light is shit depending on who you talk to. This tent and light was a cheap way for me to learn how to grow and what I need to grow with. I plan on having 3 growing rooms in my basement two for flowering and one for veg but I want the best most light for growing. Cree cob is the led in my fixture and what I have been told to use but HPS seems like the way togo

He's pulling your leg about the blurpie lights. Some guys are so against them that they blame everything on the blurpie. In my opinion you have a deficiency of some sort. leaves look small in size plus purple stems.... How's the overall size of the plant and how old?
I don't even think the Black Diamond dwarf star is a blurple. It has Bridgelux led in it
My first light was a dwarf star that seemed to do ok but I was told it was shit and I bought a 3 led cree cob DIY kit. Mostly been gown under the dwarf star cause with both lights she starts to curl her leaves.
today is 46 days. She at the tip of the highest bud is 49 inches. the picture was just taken about 3 minutes ago for you to see her now.

I would still do some digging and research your issues. have you checked ur ph levels?

Nope, I run blurple lights right now, not pulling his leg at all. I have experienced it myself. Look up anthocyanin production in plants as a defense against light stress. I know of what I speak, but I appreciate how you might assume otherwise, so many trolls and arrogant idiots out there.
I am not one of “those guys” when it comes to this shit, just trying to help.

Wow, the lighting in your photos look very purple on my iPad. My bad, no offense intended.
I seen your post and understand you know your stuff. things you've told me check out when I look up things you've said up. I really thank you guys for spending your time to help me and I appreciate y'all understanding when I say or do newbie things. Guess I should have said this is a big bud auto flower. She is holding up my white skunk and skunk #1 from being changed to flower. but I hate to not let her finish

Maybe you can enlighten us, and provide us with a link, or some sort of facts that prove your not just running your little mouth.. Telling me to "Go research" something doesn't prove your right, nor does it make me a troll. Thank you very much!

Purple stems ... no big deal and they're pretty to look at.
As mentioned, some are genetic. Some develop from temperature in the root zone.
None, as far as I know, have ever stopped a plant from producing.
Nearly all my plants have gone through some purpling.
Some more than others.
The buds are still fire.

I'm running some blurple leds, and do notice I usually always have some purple/reddish looking leaf stems. I believe it mostly to be either a slight deficiency of something or just some strains naturally do it, some more than others. It doesn't seem to be an issue though because they still finish nicely. Just a quick pic for reference, 2x4 tent 3 plants in 1 gal pots {I think they are actually 1.5?}
Exactly 5 weeks in flower

I have two white Skunks ready to switch to flower and just waiting open this auto to finish. I look forward to the regular plant and see my bud size. Maybe these will fatten up

Those last few weeks of flower is when they really start plumping up. It's always my favorite part of the ride being able to see the noticeable difference day by day, especially since most of the grow, the odor isn't too too strong {opinion lol} but in those final weeks... They need deodorant lol
My first thoughts was too much calcium. Causing magnesium lockout.
Here's an article I just found on Google, explaining antagonists.
It only backed up what I was thinking. IMHO, unless you're growing a purple strain, stems need to be green.

Don't trip on it man.
You can drive yourself crazy trying to figure out every little thing.
Plants look good.
Not all your stems are purple and even if they were ... if that's the only "symptom" ... it's nothing.
If you had nutrient issues you'd see more trouble than purple stems.

I read the heading.
I answered a possibility that wasn't put forward already. It's also what I have always found running coir as well. Barely ever happened to me outside. Unless it was cold.
I've found myself, if it's just the strain, they purple very early. Nothing will change it.
But if your stems were green, then turned purple. Nearly always it's lockout.
I've found when it is lockout. Whether it be ph, nutrient, or cold. The petiole turns purple. Closely followed by a purple stripe, down the leaf stem/petiole. If left unchecked, the whole stem turns purple.
That's what I've found. That's what I'm contributing.
You're in coir too. Could be calcium. Could be potassium. Calmag problems are very common in coir. Not for being deficient either.
Coir naturally holds an incredible amount of calcium, magnesium and potassium.
I understand you're using worm castings too?
Worm castings are naturally quite high in calcium. Potassium too.
If your coir is leeching. The worm castings are just catching it. Then the calcium, and potassium binds to whatever is already present in the castings. Worm castings naturally have a charge, and will catch cations leeching from coir, for sure.
Your plant does look healthy. It was only meant as food for thought, to answer the threads heading.
I still wouldn't count it out at all.
I've grown many different varieties. Only a couple of which I have been fortunate enough to see natural purple.
Nearly everytime for me, it was lockout. The stems go back to green, rather fast too.

First, I never said you were a troll, where did you get that?
Second, you’re rude. See below.
Here are several scholarly publications supporting my claims about light stress and purple pigmentation caused by anthocyanins.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2682507/

Here is the google results page for scholarly articles with specific relation to cannabis, related crops, and anthocyanin production.

And a fucking High Times article, it might be more your speed.

Happy reading.
Was there anything else you need proven for you today? Like maybe why the sky is blue, or why the moon has an effect on the tides? There’s this thing called science, you can even learn it for yourself, it is not my responsibility.
I was trying to help the OP, ass.
Here’s a picture, in case you’re too lazy to click a fucking hyperlink.

Thirdly; I did, however, mis-type the name of the pigment chemical, anthocyanin. My apologies for that, my latin combining forms got switched up.
