GDub51answered grow question 4 years ago All say that when they "stretch" like this the light is too far away and they are stretching to reach it. Yet I germinate outdoors and see the same thing. Lowering the light will help (or raise the seedlings) and prop the weak looking ones with a toothpick and a twist tie to brace until it matures. NO don't re-pot yet! Leave until they have a couple of sets of true leaves at least B4 transplanting. I only transplant once, starting in large Jiffy cups then into 15gal. final containers. I'm outdoor so the large containers, indoor usually smaller.
