Red stemed fan leaf

Is it true that you should trim all the fan leaves that have red stems in the flower stage ? Cause I was under the impression that you don't trim at all when in flower.

who told you that? and why...what is that supposed to do? basically why would you do that?

if the leaves aren't blocking a lot of light, touching a bulb or all shriveled up or dead and stuck inside a bud. leave em alone.
 
Red/Purple stems are usually a sign of stress. I guess it's better to solve the problem that causes the stress. I never remove stems, only the dead one's.

Totally ridiculous notion. My god, where does this stuff come from!!!!!!

So what then Keif, is all leaf stem color just genetic. No deficiency at all?

I personally don't worry about my leaf stem colors. Just not sure if it ties into a deficiency or not.

I know I certainly wouldn't remove them because of color.

Absolutely just genetics. I've had a mix of different strains in flower, some with red stems, some not. All turned out equally well, no problems at all.

Ok so we need to clear this up right now because I think what holand is referring too is the petitole not the stem. two very different parts of the plant

If you read his post


"Red/Purple stems are usually a sign of stress. I guess it's better to solve the problem that causes the stress. I never remove stems, only the dead one's."

To have remove a whole stem of a plant because it dies means something is seriously fucking wrong aha and im sure everyone can agree . red stems I can agree can be genetic such as many purples. But what throws me off is from reading everyones post I feel like you guys are referring to :

PETITOLES which are what attach the leaf to a STEM.

If we are talking about petitoles then Im sorry keif but that is so ignorant/bad knowledge being passed around.

Mirac stated :

"I personally don't worry about my leaf stem colors. Just not sure if it ties into a deficiency or not. "

Leaf stems = petitoles ? correct mirac thats what Im getting from your post.


If so im going to disagree with you plain and simple keif. 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 they will show other signs shortly after so it can be a sign that your plants are soon going to become def in my example MG. If were talking about stems the which branch off the base of the plant then yes those can be genetic related like you stated.

But we need to distinguish on what part of the plant we are referring too

If it isn't genetic, then it may be from a pH fluctuation or the pH is wrong for your growing medium.

I've noticed when I'm a little too crispy and forget to pH my water that the stems will take on a reddish / purple colour. Whoops!

If you forget to ph long enough that your stems are turning purple, you should prolly get on that
 
@Keif Stoned: Its not ridiculous, red/purple stems are signs of stress. Not always but in many cases it is, so it has no use to remove them because the stress factor is still there. Even if you remove them other stems will become purple, thats why you need to find out what is causing the stress.

Longtime ago I had a small place to grow in, in the summer I couldn't even control the temperature and I saw the stems becoming purple which is a sign of stress. I solved this by using Aptus Regulator this is the first time in my life that a product like this did actually work. Just check it out, it is pretty expensive but it lasts for ages. Still the best way is to tackle the stress factor. The stress factor could be caused by temp, nute defs, low humidity level root damage etc.

Holland,

Been running a small grow, 6-8 plants, year round for the last 12 years. Sometimes all the same strains, sometimes a mix. Often Flo, Satori, Blubonic, Skunk......ect. Temps are very well controlled, usually 78-82, separate veg room from flower. Humidity is higher in veg room, usually 65% and 35% in flower. Conditions are consistent throughout grow in both, near ideal. Use organic soil mix and all plants get the same thing. Always, some plants have purpling on fan leaf stems and main stem, some do not. Right now I have 3 casey jones in flower along with a Flo cross. 1 casey has purple showing on fan leaf stems, the rest none. Different pheno will show purple sometimes and not on others. Regardless, all plants turn out well. I just dont see how a deficiency of any kind could be involved.

Keif
 
Not all strains are the same, I said it before a lot of people can confirm this about the purple stems. I do agree with you it isn't always stress that causes this, but it can be.

Growing skunk XL atm. Branches are getting slighty red. Main stems no red at all. I believe in most cases it's down to strain. My girs are literaly exploding in growth atm. And look super healthy. So i'm not worried at all about the red branches :)

this one turns purple with age.

clone, bottom is purple new growth is green, goes back purple as it gets older.

based on my own personal years of growing weed from seed. purple petioles mean fuck all. i used to think it was a sign of a deficiency too back then.

so did a lot of people. but these days i only pay attention to what the leaves themselves are doing. anything else on the plant red or purple these days just usually means someone crossed in some DJ gear somewhere in time.

i run the same cuts over and over again and i can say for sure that some of them e.g. my blueberry cut and my pre-98 bubba will tell me that they are ready for repotting or need more feeding by the stems, leaf stems/petioles and the veins turning red (petiole first and then the red travels up the leaf vein) . when i repot the new growth is green again.

im sure this doesnt happen with every cultivar/strain, and many genetically have permanent red stems, but definitely some will. its anthicyanin production as a result of nutrient deficiency.

so if you have red leaf stems on a strain you dont know, its hard to conclude anything from it, but if you get to know your cuts then it can be a good early sign in some.

VG,

Ive noticed going into flower that my red stems are turning green, with out a repot. I wonder what that means in relation to nutrient needs? Any thoughts?

hi MM, i couldnt really tell you, it could be a different light, warmer temps, a change in feeding, or just genetic.. its hard to draw proper conclusions about these things without running the same cuts a few times, but keep making observations it can be very good way to learn your plants and get a head start on knowing what they need.
