Honestly i feel more forgiving growing in soil because im an organic freak somewhat. So in my world its easier to use soil as long as i know the soil so i can get a general idea of future deficiencies, ect if that makes any sense. Also cheaper for me. The cost of good hydro equipment in hawaii is retarded. Id say leave it alone. No more transplanting or root disturbances untill your ready for a bigger container. Keep ph within range, find your sweet spot for watering but be carefull because the water gap wil get shorter and shorter, i underwater all the time on accident. They say it wont hurt, but it stunts my flowering plant for a few days everytime i forget.
