I need advice on growing rosemary. Help, please?

I started from seed. I germinated ten plants in my greenhouse. I've moved them from their seed tray to six packs until they were large enough to go into a pot and out of the greenhouse. I've got 3 pots, two on the covered front porch and one in the window sill both of which get the morning sun. I used miracle grow soil and they still don't seem to be getting any larger. My Chervil, Parsley, marjoramand dill are all doing well. the rosemary, cilantro & chives seem to be lagging. Point me in the right direction?
