Could you post some pics of your grow room. Also what kind of lights are you using. Lighting makes a big difference in growth. How old are the lights you are using, as this can make a difference too. Also is this plant in the same container as above in the pictures? if not it could be that it is in shock from the transplanting and or over fert. Sometimes in takes a few days to recover from shock, and somtimes they never recover from shock. As for diagnosing your problem there are just way to many factors unknown at this point. Give us your statistics and we will see if we can help you. Oh, and i think Bonsi plants look awsome, so it wasnt a negitive statment.
