Red stems
NSCannaanswered grow question 3 years ago
Red stems are mostly genetics related, there's a lot of bro-science stating this can be the result of a deficiency but 9 times out of 10 it's genetics.
You should only be concerned if the branches/main stalk are turning purple, that is def a sign of a deficiency. But leaf stems are fine, especially in flower as your plant may be pushing a lot of anthocyanins (the chemical that turns cannabis/other plants purple).

red stem can happen for a wide range of reasons including genetic that you don't necessarely need to worry about.

Red stems is the cause of stress.
Your plant can stress for many reasons like change of climate, light hours,forced stretch and more.
Since it is only on the fan leafs and just a little bit of red, you should not be worried alot.
If brances or your main stem gets red, you should do some check ups but that might be a only if question + solution for another time :)
Goodluck growing :)

One of my 3 plants is significantly smaller than the other 2. Her leaves are multiple colours. She was late to shed her shell so I peeled it off myself. She is still steadily growing however I have been unable to diagnose her. The photos of her are labelled "sick one"Week 3

I believe I fixed my nute lockout a couple of weeks ago. But since flowering has started I’ve been getting a deficiency on the older leaves from the bottom moving to the top. I’m wondering if this is A nitrogen deficiency as I’ve backed off on the nitrogen since I’ve switched to flowering nutes. I’m not really sure how to proceed or if I’m even right.Week 21

In week 12 of the diary I show the continued issue with yellowing and loss of leaves. One G13 plant has nearly lost all its leaves. I think I have a pest issue, see week 11 diary picture of the pot with lots of white tiny things crawling. Could this be root aphids?Week 12

Need help diagnosing leaf loss issues with the G13 Haze strain (problem has been over 5 weeks now). The one in the smallest pot (7L) has lost a majority of its leaves. The leaves start yellowing and turning brown then crispy. They have white speckles on them like salt.Week 10

Under-watering? I water all my plants equally and one seems to be growing steadily and two have stopped. How often should I be watering in smart pots and how much water should I be using each time?
Also is there anyway to save my two heat damaged plants or should I scrap them?Week 3

Hi, anyone any experience of the pineapple express auto that could comment on how it looks? Just think its lacking something? Also would it be good to trim a few leaves from the Kush and #119? Both very bushy and have been leaf tucking but didn't want to start snipping.Week 7

Hey experts, I had some issues in week 7/8. See week 8 pics for additional clarification. Tri-lobbed leaves. Is this ruderalis genetics or am I experiencing re-veg due to stress?
Deformed new growth, which is stunted and curled. Is this zinc issue due to pH or toxic salt buildup?Week 8

Some of my newer leaves are much lighter in color and seem to be most affected by these spots, my largest plant is the worse affected. Have red stems, lower leaves are looking healthy green though so scared to give much more nutes, feeling stuck. Maybe small mites? Ideas?Week 6
