Hey Charlie-Foxtrot, thanks for reaching out. Based on your description and looking at that close-up leaf picture in image.png, it seems you're on top of your water and temperature game, which is awesome. The slight yellowing or burning at the tips, especially in early weeks like week 3, is super common and typically signals light stress or nutrient burn. You mentioned enough moisture, so perhaps we're looking at nutrient burn. What's the pH of your water and run-off? If the soil's too rich in nutrients right now, or if your watering pH is off, preventing the plant from absorbing what it needs, you can get these issues. A simple water flush might help. Alternatively, if your light is just a little too intense or close to the seedlings, that can also cause the tips to light-stress. Try raising your light slightly and check back. Don't worry, these issues are usually easy to fix when caught early! Happy Growing Growmie🌱
