Balcony Grow II

Lets see. Since they are outdoors, you can't do anything about the temperatures, since they are a little on the low side, that will make the plants grow slower. As for water, you are over watering, a lot. Soaking the whole pot is too much at this point, they will take weeks to use all that water. Seedlings at this point need no more than 40 cc of water per day. Just let the soil dry before watering again
