Ive recently switched my plants to 12/12 to enter the flowering stage. when i did this, i moved them about 5 inches away from the light keeping them at 13" away. Before I did this they had grown to be about 3" away from the light so thats why i moved them. The problem is now I noticed the plants all sagging over. Everything looks like its bending downward not like before. what do ya think?
