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.
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
also how can i post a picture of my setup?
