Red stems

Having problems figuring out if the red is genetics or cal/mag problem. Running animal cookies, strawberry glu, and cookie glu. Wondering what your thoughts were.

Some red is fading after using 4 ml of cal mag in ro water, last feed cycle was 1mlbase nutes 1 ml calmag

Genetics, my plant does that too. It’s a crossbreed.

Yea some red just isn’t going away. What strains you running

Red stems are stress, healthy stems are always green. Your not going to get everything perfect so it happens i suppose.

I just give up on the red stems, I’m going to try to raise my lights.. doesn’t seem to matter.. I’ve even decided to raise a plant outdoors just to see if it will make a difference.. I also believe it comes from temp to a degree though.. either way I’m yet to raise a plant without it..they start out green but always goes candy red... is really like to know wtf I’m missing here..for the most part the plants survive...

dont stress its a weed - wont hurt keep pumping the water/food she will be right- everyone has purple stems -

Red stems are not always stress. Red stems can be genetic. In fact I think genetics are the main player in red stems. If the rest of the plant looks fine don't worry about the red stems.


Here's a landrace I recently grew. One of the characteristics is red stems.

Genetics: Mazar-i-Sharif Landrace
Sourcing: The Real Seed Company, via Afghan charas and seed merchant, Peshawar, 2007
Purpose: Charas (sieved resin)
Latitude: 36° N
Harvest: October through November
Height: 2–6 meters outdoors
Characteristics: High-yielding, tall, intensely resinous, red stems and stigmas, Indica- and Sativa types, CBD

A lot of strains have red stems from genetics.

My best shiz is always red stemz.

Genetic in that the plant has the ability and precursors present to induce pigment formation to reduce oxidative conditions from many abiotic stressors and protect chlorophyl which is grern.

Otherwise a stem has no point in turning purple just as a healthy leaf also has none.

Yea I understand it’s nothing to trip about, the plants are healthy and still praying in the morning and sagging before bed. Sometimes I guess I just misunderstand how complex growing any type of plant. I come from chemistry so it’s a whole different beast

It's because of anthocyanin which is present in all cannabis plants. It's what makes purple strains purple. Some strains have more present than others due to their genetic background.

I think if you turn it around it will make more sense - some strains are more susceptible to steess and their genetic background is always to produce green stems and leaves in a perfect environment.


If you take a tropical sativa and put it in a colder environment id gues anthocyanin will be just one of the many pigments that start to show up - i wouldnt say thats a breeding trait we can genetically alter.

How does that explain landraces that have been growing in the same regions around the world that develop purple? Even tropical sativas growing in South America will display colors. It's genetic. It's not always due to stress or cold.

Of the few types of similar genetic exspression threads recently members have tried to convince me that it actually possible to breed a red stemmed hermie polyploid strain easily.

The context has surely been taken too far when a well grown naturally green non hermaphrodite mon mutated strain and plant is artificially triggered to show all the red stem hermie mutant growth just by treating it badly that others describe as genetic.

Lets take a sec to quantify Faustin024's original plants. Wow nice well grown but can we say they are 100% perfect or more like slight room for improvement.

So if he is just slightly of perfect and he gets a few red stems dosent that add up, why would we tell him its genetic, his plants are good but perfection not quite.

Thats the context part, people seem to eager to believe in the 'out there' ideas, this seems to make a lot of opinion and mo one agreement.

There are strains, Pakistani Chitral Kush that will grow purple without stress, cold, or other man induced factors to cause coloring. I've grown it numerous times. Most are purple but a few will be green. I've had both growing at the same time. Same seeds, same growing conditions, no stress and no cold. Give that strain to 100 different growers and 100 different growers with 100 different grow conditions will grow purple plants. The color is genetic. There is no disputing that fact.

All I said was that the purple stems can be genetic. That's a fact. You seem to want to keep going on about how it's a certainty that it's due to stress when that may not be the case. Maybe it is in this particular case due to some environmental factors but you don't know that. I never said it was due to genetics I said is was possible that it could be due to genetics.

Im sorry ive seen a lot of purple strain hype but most just came out green to the good growers and still do start to end.

Should a flower or trich take on a purple exspression well that would be a seperate discussion.

If the op finds that little extra the stems will revert to green and new ones stay green, if they take a turn for the worse they will amplify.

Just genetics is a poor answer, discussed nothing but made others carry on some weird belief. If only you could debate the reason a living green plant feels like turning leaves and stems purple as if for no reason.
