How much can i get from a small outdoor plant?

I have a 7 week vegg old kush plant from seed that went on the ground mid augest, it was 8 inches tall, topped and transplanted to the ground a week later it is like 13 inches, with buds growing. Im afraid i wasted my time as the plant looks like it wont yield much becuase it stopped growing and stems are still small and scrawny lookin, but turned grern rather than the purple stem look. What does the yield look like? I seen a guy use a cfl refrigerator and vegg for 25 days than flower 30 days than went outdoors and got 2 oz a plant. It will be sad if i dont even get half of wat he got and im using the ground and a much stronger ligh to vegg.

Sounds like an ounce.

its never a waste of time to grow buds. I think you will get a good amount
