It looks like a young plant. You can harvest now or let it mature a little more. Did you plant from seed or a start? If a start did it have a baby pepper or flower on it when you planted? I don't see any flowers on the that plant. What about the other plants? The plant looks healthy. Have you fertilized? If you have and you used a high nitrogen fertilizer that may be an issue. High nitrogen will push a lot of foliage growth instead of flowers. Be patient - it is still early even in Georgia.

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. ~Author Unknown
