Plants bolt when they flower and go to seed. I assume that your seeds haven't flowered yet, and are simply spindly?
If so, the problem is lack of light combined with too much heat. Once seeds have germinated they do best in a cooler place - too much heat will make them grow too fast and become leggy.
What kind of seeds did you plant, and when?
