What kind of light and how far away is it? I've never seen that much space between the cotyledons and the first true leaves. If it's fluorescent, you should be only a couple inches from the top.
i had the completetly wrong light until a few days ago so thats why its spaced like that, lol yeah it was my fuck up but every since i put it under a shit ton on watts its grown alot in just a few days!
