Red stalks in veg??

[sidekick20]

In my veg tent...my main stalk and branches that I would clone have a red Outer like layer on it...what does this mean?

Some plants show red stem and petioles if night temp goes low, some show it without a reason and sometimes it could be an indicator of something nutrient-related (often the leaves fall easily if touched) but if the plant is sane, green, healthy, forget about it.

possibly cal-mag defficiancy also.

what noreason said...some just take on that reddish-purple colour no matter what.. Does not mean there is anything wrong. That is if the rest of the plant looks healthy and all...deficiencies will show up on the leaves as well so if nothing goes wrong within a day or two.. don't worry too much.....actually, don't worry at all..

Thanks guys I was starting to stress out...ill give it more time take some cuts to see if they root

Typically, reddened or purpled petioles, assuming all other parameters are met (temps, RH and light), can be an indicator of N- or P-. Cold does indeed cause this, via locking out these minerals.

Go to my albums, look at my charts and graphs album. Go to the graphic of cannabis leaves to begin getting an idea, but be certain to look at the flow chart. Also, use .edu, .uni and those sorts of extension sites for information on symptoms. I may have another link discussing this, but I'll have to look around for the right one.

some plants have red sap:

I would not use red stems as a rule for nutrient difficiencies unless you have grown this cut before and have experience with it. Too many strains exhibit this characteristic for many other reasons. Like stated above it could be from genetics, cold, nutrient difficiencies, heat ect. I would look at over all health and leaf signs as a method instead. Just my opinion.

Cold can cause what appear to be deficiencies, and in a very real sense they are deficiencies. Just as pH needs to be in the right range for access and utilization, so too does temperature need to be within range, or the nutrients cannot be utilized.

However, I do not discount those petioles. I see reddened petioles in cannabis more than any other plant, and I've been able to eliminate it pretty easily, even in plants that were said to trend towards purpling (not reddening). I feel that those colored petioles are indeed part of the overall health indicators.

Avinash, that's just scary!

There could be a lot of theories about the reddish petioles of some plants IMO and one of these could be that the color come from anthocyanins, a common kind of flavonoid that cover the young petioles without clorophyll or wax, to protect them from light...

Who knows.... maybe multiple reasons are involved?

If your stalks are turning red....and....getting very woody(hard)...you have an issue. I have had this problem a few times....and I have found it to be an excess of Phos.

Look at these red stalks.. What shall i do?



If the plant appear healthy..Don't trip.. Your good..

 

[Avinash.miles]

plant looks healthy to me.... no dark purp. stems like in a def.
so i would consider it genetic most likely.
