If this is a light mix soil you should start giving nutrients after 2-3 weeks from seedling. When it is a heavy soil you can start giving nutrients after about 1 month. Yours is just 2 weeks old so everything you fed her till now is actually too much. Keep the pH between: 6 and 6.5 Keep the nutrients to a minimum. And do not water too much. Wait till the top layer of the soil dried out before you start watering again. She will soon start to pre-flower and that is the time that she start to get hunrgy for nutrients and water. But till than keep it to a minimum.
