Hey guys, I've been trying to grow several things from seed in containers on my patio and while my leaf lettuce completely exploded in growth, my swiss chard, spinach, and dill seem to have gone stagnant or not sprouted at all. The dill are seedlings about 3 inches tall, and the spinach and swiss chard about only about 1-2 inches tall now. I haven't seen any new growth in the last week and half! Is this normal? I'm betting it isn't but haven't determined the cause. I don't think I'm over watering and I read somewhere that it's unnecessary to fertilize seedlings. What could I be doing wrong? They get around 6 hrs of direct sunlight a day. Any help would be appreciated!
