Auto não cresce e esta amarela

I have been growing outdoors for close to 40 years and can tell you that this is not caused by either high or low humidity or high temps, rather, some seeds just don't make it and this is probably one of those that just isn't destined to be a good grower. It happens, not all seeds are perfect. Even seedlings at 45+ degrees Celsius outdoors don't go yellow if they are genetically strong in my experience.

Best to add a dome to keep humidity high in this stage. She'll take the temperature better that way. Also keep an eye out for the soil drying too much or too long.

Hey buddy I just checked your diary, it seems to be low humidity and high temps, high temps can cause that yellow leaves. Such a young plant is very sensitive, especially if you have different phenotypes. They will not react the same to your outdoor conditions. Try to keep her away from high temps, 29 at that stage is to much. Hope it helped Good luck with your grow buddy
