stickdawg, do you have a gentle breeze blowing on your plant? It will help to thicken the main stem and make it stronger. Will you be doing a transplant? If so, I suggest you bury it a little bit deeper to cover up some of the long stem. Thirdly, after two more sets of leaves, I would consider topping it to get some lateral growth started.
Overall, plant looks nice and healthy. Good start!
