Looks like they are seeking more light. My suggestion would be to get them under the fluorescent lights at about 4" above the plants. You can turn them each day until they straighten up. I would also suggest you use a fan to move the air in the room. It helps to strengthen the stems. You don't need the fan to blow on the plants, but just above them. Remember you can plant them deeper in the ground then they grew in the pot. It's one of those rare plants you can do this with.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
