purple stems

[Guest]

what up with purple stems why does that happen and what is a good organic remedy

 

[chewygobstopper]

It means the plant has a high thc content, no need tow rry.

Some plants develop red stems from the cold temps, and I have heard that others get red stems from nutritional deficiencies. Use the search feature and you will find out. I believe some red stems are strain dependant.

(It has nothing to do with THC content!)

Like these...?

This is Flo, outdoors in the UK. Stems don't get much more purple...

whoo those are some purlpe stems!!! i guess my prob is not that mush of a prob then just looked kinda funny to me.

BWAHAHAHAHAHAHAHAHA, thats fuckin hilarious. i hope you were joking.

 

[jcsmooth]

If he wasn't joking, does he ask his dealer for only stems?

Elevator Man...those are the most purple stems I've ever seen. They almost look like this purple licorice I used to buy when I was a kid. Okay...I still buy it, but I'm not a kid anymore. lol

I wouldn't worry too much about purple stems, so long as you don't think the plants growth is harmed in any way. Purple stems can just be a variable of genetics, so trying to "fix" it would be futile.

On the other hand, I noticed some of my plants were getting purple stems and then veins in their leaves. I used a friends PH meter and found out that it was pretty low. A little dolomite lime sprinkled on top (or dissolved in the water), and the plants were less purple and vigorously grew. I don't have the most growing experience (just four grows under my belt), so maybe someone with more knowledge and experience can help you out.

Good luck, hope everything is good for ya,
JC

the ones i have seen were just a little red to pink not in leaves i cant get over the flo that is the craziest herb i have ever seen novelty alone would sell that girl seen purple star blue berry and a few other kinda diff coler strains but not on the stem like that i want some

Im suprised no one has said ph... although some strains do it with age and maturity, if your having purple stems early in the veg phase its most likely that your ph is off. Ive been able to correct a few plants early on, in fact i usually calibrate my meter when i notice it with newer plants.... The GDP in my gallery was a perfect example... i had the worst ph problems with that plant because it was my first attempt at a soil mom, the ph was all outta wack and the stems were purple as could be, but i got her straightened out and she became green again... you should see it now! keep it easy ~caddy

Err... I think I mentioned it.
Like I said, I don't have much experience with growing, but I do know that once I boosted my ph to a better range, the purple veins went away (although the stems are still purple, leading me to believe it's just genetics. They are as healthy as an ox).
Anyone else think it could be ph?

I have some troublemakers going right now. The stems on those are getting purple all over. Mostly the top of the plants though. 70 during the day, 55 every night. Very steady. The TM is a kush/skunk cross, I believe it's a genetic trait with them. Varies though from strain to strain, and indicators of little issues here and there as everyone has suggested.

Try and find out as much about your particular strain as possible before and while growing it so that you have a good idea of what to expect when things like this arise.

Those FLO stems are too much Elevator. WOW, pretty freaking cool man.

Spaced...

Hey JC, good call... my bad not getting through your last paragraph... More proof that speed reading and smoking pot dont mix!

 

[SpanglyBoovus]

in my experience purple stems can be either genetic (no worry here), ph related as stated above, or nute lockout/deficiency (possibly because of pH related problems), or temperature (cooler temps can bring out purple hues in cannabis varieties which is also somewhat genetic)

The likely answer is genetics though, as Ive had many plants that have purple stems and turn out excellent. The only time I worry about purpling is if the plant is showing other signs of problems like stunted growth which means it's likely pH/nute related..

If your purple stemmed plants are otherwise normal, then learn to love the purp.

 

[Farmer Joe]

I've had some plants stems (mostly on the fan leaves) turn purple/redish and some dont. I wouldnt worry about it if they are growing fast and look healthy.

 

[hanfiking]

There are loads of different threads here IC about purple strains, I have one myself. with lots of good information about why they turn purple (due to anthocyanin) and motaco himself posted a good read about the purple hype and a cut out of history.

i have always considered a purpliing of stems and veins to be a phophorus defienency. I learned in my plant nutrition class that this is a common symptom to watch for. as for the pH, well pH directly influenced the absorption of nutrients. if the pH is too low or too high nutrients can get locked out and deficency symptoms can arise. late in flower is it common for def. symptoms as the plant is trying to give everything it has to its bud so its next generation will be that much better off. I would do some research bout purpling stems. granted, all the reasons for purple stems stated were accurate...just not what si wrong here (i dont think) i find it hard to belive that most pics i see with people having purple stems is genetic, or even temperature dependent. it is most def a defecency symptom. i have purple stems on my ladies right now and the temps are perfect and so is the pH...i just need to add more P

try and find this book...it will help you out so much....
mineral nutriton of plants: principles and perspectives. by Esptein/Bloom

it covers everything from nutrient defiencies to hydoponics

My latest clones about half have purpling stems and a couple even the leaves. Like I said only about half are this way and all were treated exactly the same as far as nutes. light and soil. I don't think the temps could have caused it either. I was just letting them go the purple color doesn't seem to hurting anything and it looks ok too.

 

[jolene]

Those look beautifully healthy - looks like a wierd genetic thing to me.

 

[hanfiking]

Flos are always like that, some purple stems are signs of deficiency. but you can tell which ones are supposed to be green are turning purple and which are really purple and are supposed to be, genetically.

Purpling can be caused by a deficienty in Potassium, it's a commonly overlooked element in organic grows and can also be locked out by some soil ammendments peeps use in the wrong quantities like dolomite lime.
Cold temperatures lock K out, some strains are more succeptible than others to purpling but essentially it has to do with the uptake of potassium on some level.
I've noticed that strains suceptible to purpling like Blueberry are not the most yielding strains I've grown (although potent), but I find the assumption that organic grows are less yielding is due to the improper handling of K in some growers' mixes.
