^^^What Tammy Sue, the Melonator, said. They look to be searching for their energy source.
I see a heat mat beneath some of the containers. Are you still using it or just haven't removed it yet? I would think you wouldn't need it now.
Something you might want to do to enhance your LED grow lights performance is to hang some mylar where you have the blue tarp hanging (hang it over the tarp if you want to, it's lightweight). It will reflect a lot of the wasted light coming from the grow-lights back to the plants. Look for cheap "emergency blankets" in the camping department at Walmart or some other department or sporting goods store, they work well. Also, rigid foam insulation with foil backing (even with printing on the foil) works well and can actually create a semi-insulated pool of air around the plants...it's easy to stand/prop up if you get 5/8" or thicker sheets....3/4" works nicely. Even just a solid white sheet of "something" to reflect back that lost light will work better than a dark surface.
Hopefully before long you'll get to move them on out to the garden where they can reach for the sky!!!
