I have some seedlings and some are starting to wilt while some of them grew in an odd way, it's like they grew too long and can't hold themselves up. They are only two weeks old. I water them and keep my lamp far enough away so it's not too hot but close enough to get the benefits of light. Will they start to strenghen their stems or can I do something to help them? It's like they are leaning against the soil yet growing some leaves still. Its like some of them are too weak to hold themselves up. Any advice for a noob?
