Hey growmie... A Magnesium deficiency can cause reddish purple stems. A good cannabis-friendly nutrient system has a significant amount of magnesium, but if you're using very soft water, or RO water, you may need to add a Cal-Mag to your nutrient regimen. Temperature – Heat or especially cold can trigger red stems in some places also. Sometimes it can even be genetics. Hopefully this was helpful and remember Happy Growing and Free your mind one puff at a time.

Hey there, bro! 👋 The reddish leaf stem indicates a phosphorus deficiency. A phosphorus deficiency can occur due to a lack of phosphorus in regular watering or because an excess of nitrogen blocks phosphorus absorption. You're not in a critical situation, there's no danger to the plant. Stick to your feeding schedule, but don't overdo it with nitrogen (N), as it can worsen the phosphorus deficiency a bit. 👌😇👍 Good luck, bro! 👋

It's going to do to be either genetics or slight sunburn from your lights. Nothing to be worried about at all! Happy Growing! 🤟😜
