Yes, this could be because they are not getting enough sun. If you notice that they are rather leggy, then it is without a doubt not enough sun.
You may want to try placing a mirror near them positioned so that the sun hitting the mirror will bounce back onto the plants. This will help get them a little more light.
It may also be a nutrient issue. Try giving them a little water soluble fertilizer too.
