I've been wondering about stunted growth too. I took some clones out of my clone dome put them in soil... and they have grown slow, very slow. Clones that I took 2 weeks behind the "possibly stunted" ones have already past them. My "stunted' plants look alive still. I am giving them time to see what happens. I mean I got nothing better to do. I think it might be that I just took smaller cutting the first time. All my other plants in the room are going fine. (This is my 3rd grow, back2back2back.) I would like to see what people have to say.
