Purple main stem?

So It started off small, I just noticed it about 5-6 days ago.

I notice it keeps getting worse and traveling up the stem to the main cola, along with spreading to the fan leaves and side branches.

It's a very dark purple color, almost like it's bruised and dying, but the plant looks healthy in general?

The strain is Fastberry from Fastbuds, it is a blueberry strain but I don't think this is a common trait?

Any ideas?

I mean it's pretty noticeable in the first picture, the second two pictures were mainly to show that the rest of the plants look healthy... but here's a picture without the blurple.

As well as medium and your nutrient game if any.

Happy Frog and Botanciare PBP line, using cal mag and bloom soil formula atm. Not much.

It's on day 15 of flower.

Ok so a plant will present purple for a few reasons...
Phosphorus lockout due to cold temperatures or too low or too high Ph in the soil makes P unavailable for uptake.
Guys are suggesting a DNA trait causes purple also. I'd do some reading as I don't know much about that.
I do know that my grows in fall when the temps are cooler make my plants leaves, stems and especially the buds purple and reddish. I think its cool and never do anything to try and change it.
It definitely helps the bag appeal.
Other than the color your plant looks healthy so I wouldn't be worried nor would I try and change anything. If you're fertilizing with a balanced fertilizer you're good to go.

Ok good to know thanks, I wasn't worried at first but the past couple days it's getting purple all over!

But like I said everything else looks great, so I wasn't sure.

I do not want to suggest changing anything in your nutrients as your plant looks healthy.

I have noticed Stems Purpling, and then going green again after a CalMag Feeding. So possibly a very minor sign of low CalMag (but I would NOT call it a CalMag Deficiency).

Or it could be either of what Hotrod or Danny mentioned.

IF everything is to a "T", then chalk it up to genetics. (Blueberrie, Purple, Pink Strains, Etc. can show interesting colours sometimes.)

Looks like genetics to me, I have a few strains/phenos that have that trait, one of them is purple through and through. But that also looks like a re-veg which could have something to do with it.

I was considering cutting the lower nodes/leaves off so the growth is focus on the colas.

Is that a bad idea consider it being an auto and since she only has a few weeks left?

If this was a photo I would normally, but not sure since it's late into flower as an auto.

I would check the ph first. If everything is fine there you can cross that off the list. I would also add some epsom salts to your feeding to get som Mg and S.

I just fed it yesterday, about 3/4 gal of water. I use 11ml pbp soil bloom and 3ml cal mag. I pH it to 6.2 and it was about 825 ppm going in.

I never check waste anymore because it's never been accurate for me checking that way, the ppm is always something crazy like 290x10 and the pH will be around 5.0-5.5 but the plant will look healthy so I just pH what I put going in.

Havent you seen the photos for fastberry (its supposed to purple aka its in its gentics). Youll be fine bro. Nowadays purpling anywhere is a genetic expression(usually). You need to have P, and Mg deficiencies on lockdown to be able to tell if its a deficiency symptom.

do a slurry test. If this is a ph issue you should try to catch it now before you do have a bigger issue.

I did a slurry test and the pH was at 5.9 so a little lower than I like it, I usually have it at 6.2 going in but it is soil as well. PPM was 825, so seemed at the point where there shouldn't be any pH problems.

Thought it's definitely a possibility, rather be safe than sorry.

Magnesium deficiency is what you have

You're right lol.

Came home after work today and some of the leaves have a calcium deficiency, little rusty brown spots are on the leaves and it just happened overnight.

Fed them 2 days ago and added 3ml of cal-mag along with the 11ml of botanicare pbp bloom soil formula, I guess they're feeding heavy on it right now to be showing deficiencies 2 days later. I'm going to water them tonight with another 3-5ml of cal-mag.

The plants need the most cal-mag in the first three weeks of flower. You should cut Ca/mag supplements by week 6.
