I would not tie a stick to that seedling, you want the stem to strengthen up on it's own....That stick is only going to make it dependent. And it is doing that because it is stretching for light + the fan blowing(Which will help to eventually make the stem strong). I have this happen all the time with seedlings I put far away from the light, but they fix themselves up from my experience, and usualy stop stretching when moved closer to the light.
Dont Worry! :booya:
