One red stem

[Willyd]

hello family so today I looked at my Chemdog millionaire clone and noticed there is one very bright red stem I’m curious is this a sign of heat stress? The temp In my tent is 30c during the day and 23c at night with the rh at 45-50%. My lights are 2 2000 watt LED and 1 1200. There in super soil and get fed kelp every other watering this one is still only getting an oz of water every 3-5 days with a spray in between. Ph of water at 5.6.

Some strains do this, many do it when exposed to light, it can shortage of K. I myself would not worry with it.

Purple petiole is common in all kinds of strains. The purpleing of the stem is most likely genetic but some issues can cause it too. So it’s not considered a a symptom unless many other issues are occurring
