when thats happened to me in the past I just top up the soil to the top of the pot problem solved. its stretching out for light as your light must be too far away. I got a heat shield now sitting right under my bulb on my hps which I got from ebay for a few pounds. best few pounds ive ever spent. as you can place your light just a few inches away from your seedling without frying it.
