I would agree that is sounds like they are stretching/lights are too far away. And i was thinking since its hydro and you cant bury them deeper.. slice a plastic straw down the side to wrap around the stem to prop her up until she can stand by herself.
What light are you using? It's probably time to get them closer. This floppy thing is not a big deal -- you can brace them up by stacking up soil next to them. I've also fixed this by propping them up with a piece of cardboard with a notch cut into it. Once you get your light closer and they mature a little bit, they'll get stiffer. Better to flop at first, than it is to burn them.. so all's good.I have some seedlings that have fallen over after they reached about four inches tall they seem to still be growing after they fell, I need some advice as to why this happened please
