She is searching for a lightsource ( sun or lamps).
Just put the pot closer to the window.
Since she can only get a few hours of light a day, she stretches meaning you get a long weak sterm.
What can you do?:
- You can try to put a fan closeby so your sterm will get thicker.
- Try to turn your pot 180 degrees everyday so it will grow up instead of going to the left or right like on the picture.
- Carefully put it in the middle again and add more soil in your put so it gets some support from it.
You don't want to add a stick to support your plant yet, it will get lazy and will not make a firm sterm.
Good luck growing :)
