Red stemed fan leaf

Miraculous Meds · Oct 13, 2014

Hey VG,

thanks, good call, it could be any of those things u mentioned. Just the first thing that popped in my head was that I didn't give them what they needed because they were purp/red and then most are turning green.

I know ive read these gentetics do this but I always think environment or stress issue first.

DrFever · Oct 13, 2014

It can be caused by a number of things from poor soil,,, drainage issues ,, temperatures, ph , not enough lighting , insect damage .genetics

Miraculous Meds · Oct 13, 2014

How about genetics that make it more finicky, or susceptible to show deficiencies? I know that statement still comes back to the genetics, but what im trying to say is that maybe if I learn exactly what they need they wont start out with a purp/ red stem in the first place.

I will say that I have ran dozens of strains that don't show purp/red stems. And with the breeder and genetics that do start with purp/red stems, all his inline strains start red for me, but his outcrosses all started green.

If you forget to ph long enough that your stems are turning purple, you should prolly get on that

It was a single watering that caused the pH fluctuation and the red stems ( the leaf stems are a shade of red, not the stalk ).

Have great respect for everyone's opinion who has contributed in this discussion and regret a harsh comment made in an earlier post. I guess I just have a bit of a 'mother hen' bias from the suggestion made that red/purple stems necessarily indicate a serious problem that needs immediate action. Above is a Casey Jones at 50 days flower and shows what I believe is being discussed. I've had no problems at all with this plant and couldn't be happier with the results to this point. Buds are starting to threaten to break limbs and I still have maybe 3 weeks to go.

I also have 3 other plants in this grow that are showing none or very little red/purple, doing well also. All plants have been grown under the same conditions, same soil and watering cycle.

If i'm missing something here please point it out.

On an otherwise healthy plant in flower (and by healthy i mean perfect leaves and vigorous growth) with deep red/purple LEAF stems more than likely means the plant wants more MG.
I have a few purple strains where the leaf stems turn purple but inevitably with my non purple strains if i get red leaf stems then i know they need more MG. If the leaves are pointing up towards the light (as well as red leaf stems) the that's a sure sign of them wanting more MG than is available. That's been my experience anyway....

With all this nonsense in all the forums growers are getting worse by the minute. It was a lot easier before we had internet.

DONAJTHEIII · Oct 14, 2014

Bubble its not nonsense and quite frankly these forums help alot of people its a form of communication. So keep your biased opinions out of this thread your statement helped this thread in no way.

Its nonsense how growers are getting lazier and cant read a little to find out more about a plant that I and many others find enjoyment in. From your statement above you seem to be the type of grower that doesnt care about the plant's health which directly relates to the leaves and other physical features you just are happy with any bud you get which is totally fine but dont come into a thread with a negative opinion when people are asking for help on a certain issue. We care about this plant and try to give it the best possible life from start to finish. If you dont know the answer or have an educated guess keep the comments to yourself.

W/O these interent forums you would still be pissing on your plants and im sure alot of us would be too lol

If that was true I would keep my big mouth shut.

You are one of the guys spreading the nonsense, that is why you felt spoken to. You say stuff like:

My petitoles will def turn purple/red when the plant is asking for certain nutrients such as MG for example and that is straight science proven

and look what happens, forum dynamics:

Guess now it is official.

In reality purple or red stems -or petitoles if you like- are by definition caused by stress. Removing leaves increases that stress.

VerdantGreen · Oct 14, 2014

mid to late flower, stems/petioles turning red are nothing to worry about imo. the plant is relocating nutrients from leaves and staring to senesce. my post above was referring to plants in veg.

i think the point here is that there is not any hard and fast rule to red stems that someone can sum up in a sentence - which will apply to all plants. it can be genetic or any number of things. it can only be a useful indicator when you know your plants well having run them a number of times.

hey VG,

Thanks for putting the matter into context. The color in my plant definitely didn't appear until well into flower and I knew I had the cal/mag needs covered. It would be great if the red/purple effect were a more certain and consistent indicator across the board. Would be a great troubleshooting tool.

BTW, just started a half dozen of yours and Mr. Ggenes Cherrybombs, gifted by a very cool friend, Cool Moe!!! Really stoked about this project, should keep me out of trouble for months.

Appreciate your work in keeping this great strain alive!!

lol I bet almost everyone here on this forum got his knowledge from the internet. There are tons of growguide videos/books, tons of articles and you can communicate with the entire world.

You can learn a lot from other peoples grow and their methods, and have you even forgot about the wide variety of online growshops.

You hadn't any of this before the internet. Just saying.

no problem keif, yeah i only use the red petiole and veins as an indicator in veg really, and only with certain strains... although i will say that most of my plants show the phenomenum i described above. i veg with 2-3 up-pots so i get to see the changes as the roots fill out the pots... and obviosuly other stuff like cold temps will cause anthocyanin production - although that generally shows in the outer margins of the leaves first

GL with the CB - some proper old school weed there, well worth preserving and good for crosses as well.

So you say im feeding BS and then quote another member's post that completely states what my previous post says. Your response makes no sense which is why I called you out in the first place your post didnt help anyone just like this one lol So yes my previous statement in fact was legit as plenty of other members here have agreed and posted similar responses.

Im not trying to be an ass just think before you type and be able to recognize when your wrong. Its not like everyones perfect.

Generally, my experiences with red or purple petioles most closely align with that of VG's. If it wasn't genetic, it usually resulted from a plant being rootbound, deficient or stressed in some other way.

After looking into this issue a bit, namely because of the shit storm it brewed up a while back in the organic soil forum, I'm starting to consider Sulfur deficiency specifically as the culprit, when rootbound & stress are not likely causes. It's something that I think many people overlook, mainly because the general consensus on this issue is "it's genetics, stupid!" Not a very sophisticated approach, nor a logical one, either.

From Principles of Horticultural Physiology

Sulfur deficient leaves are often narrow with their veins exhibiting more chlorosis than the lamina. Veins and petioles often show a distinct red color.

From the University of Queensland & ACIAR

Sulfur deficiency results in purple or red-brown pigmentation which may develop on both young and old leaves. In cultivars with normally green shoot tips, the petiole and margins of young leaves may become red, and this may extend in a mottled pattern over interveinal areas of the upper leaf surface.

I know, cut & paste... I'm such a hack.

The thing is, with that (S deficiency) possibly being the case red stems themselves would not be the only issue. You would have narrow leaves, brittle stems, et al, but that doesn't preclude red stem from being an early onset sign of S deficiency. Rather that there are a variety of physical signs and red petioles is but one of them.

So, again, it is only something to consider when other possible explanations (genetics, environment, rootbound, etc) have been eliminated. If you're only seeing red petioles it's likely not a nutrient related issue, and possibly to due to some other cause(s).

But then I worked at the Thuiskweker

where everybody used to get his info from.

Don't get me wrong; the internet is a great place to get information! It is just unfortunate there is so much disinformation as well, which makes that a lot harder.
In "our time" we used to listen to growers with decades of experience, nowadays we listen to growers with more than X posts.

Here is a very interesting video that explains what causes all this stress: http://collegerama.tudelft.nl/Mediasite/Play/600a5501-0fe9-4b41-9ffe-876f2a8b89cd
It seems boring at first, but it gets more interesting the more you see it and think about it.
Unfortunately it is in Dutch, but the illustrations are in English.

We Do listen to growers with decades of exp. which go hand in hand with the post #'s for the most part and if their phony their rating will go down. Anyways the mag just lets us all interact and communicate with each other across the world. It allows growers a chance to connect with one another which many of us wouldnt get the chance to without the internet.

The internet/technology has cons yes I agree but in this instance I dont really see a con aha

The mag is home and has so much to offer.

I think youll change your mind once your around a little longer

Lol yous crack me up

Miraculous Meds · Oct 15, 2014

I wonder if the OP got the answer he was looking for. LOL

stihgnobevoli · Oct 15, 2014

he already did. unless you can see some other cause, it's most likely genetic. deficiencies are from a lack. if his plant is lacking he would know it. well maybe not. but it's gonna be something more definitive than purple stems. i've had multiple strains all in the same environ growing in the same soil some might have purple only right at the middle of the leaf where it connects to the petiole, some will have stripes along the main stem only, some will be all green except the petioles, some all purple except the petioles. if the plant isn't giving you any other indication of having issues then don't worry about it.

the most important colors to look out for on leaves are, green, yellow, brown, and white. in order of importance in my own humble opinion.

green leaves = great. yellowing leaves = merely ok, yellowing and browning leaves = bad. leaves turning white = DANGER WILL ROBINSON!!

if i see any other colors on the leaves themselves they are a result of one of the other stages above.
