Hi Maria, I think we already taalked About your Lights, Iam quite sure your Plant is fine. You can regulate a lot in the lightdistance, if Girl gets too stretchy just lower the Lights, if they seem to grow very dense and with ashort internodial distance, the rise the Light. Greetings.
You can give her some Airflow and some stemfattening Training. Just shake her everyday a Little and soft so the stem gets fatter,Same to the Airflow, Plant should shake softly in the Airflow, to develop strong branches.
