Clearly they are no getting enough light, plus you need to work on your watering habits. Water the plant, not the pot. At that stage, those plants only need a 1/4 cup of water at the base of the stem every 3rd day. Anyway... if you look at your plants you can clearly see those (2) problems have caused your plants not to even begin popping out secondary nodes, even though they already have 5 - 6 main nodes. In general, when a seedling hits its 3rd main node, the 1st nodes side branch should have already popped, which none of your seedling show as happening on any of their main nodes. So like I said, drop the light, and use better water habits, so those babies can truly come back and reward you for all your hard work!
