Red stems can be due to deficiency but its not your case.. yours Is Just the genesi that run in the genetics

It's cool, your plant looks fine, that red stem is normal at this stage. Take some notes, you know, it'll be easier to find mistakes and answer questions later. Without data, it's like reading tea leaves, you know? Good luck!

Red stems on seedkings are completely normal and not an area for concern.

Hey! 😊 A red stem on a young seedling (especially in the first week) can be completely normal, particularly for certain strains like Green Gelato — it's often a matter of genetics. 🌱 However, it's also worth paying attention to a few things: Does the seedling have the right conditions (temperature, light, watering)? Is it too close to the lamp – too intense light can cause stress and discoloration. Is there any deficiency (e.g., phosphorus) or excess of nutrients? If the seedling looks healthy (leaves are green, not wilting, no spots), then everything is probably fine. Keep an eye on it – young plants change quickly and often "fix" minor issues on their own. ✨ Good luck with Green Gelato! 🍀
