Oneder,
You said you had a fan? I did not see it in the pics. make sure you have it blowing directly on the seedlings to keep them short and build strength in the new stem.
You also need to construct some kind of box for you babies.
But first thing you need to do is get those 4' lights mounted to boards and hang them from the ceiling or something and put them about 4" from the top of your plants.

get that done and read as much as you can
in the FAQ section.

LOL and happy growing
