Sorry teenagekick5, I must disagree with your fertilizer answer. As too much fertilizer doesn't cause stretching, it would kill young sprouts like that. If the plants were near the window, then they are not getting the light they need. That's why the stems stretched. CrystalBaller, you need to prop those plants up before the fall over. Get that light nice and close and keep it on 24/7 for the veg phase. You don't want to add any fertilizer until they have their 5th set of leaves. Meanwhile checkout www.overgrow.com they have a great section on growing with lots of information.
