i am answering your question about your fallen over sprout in this thread, cause you made it sound like you looked at this one more often. I think the seedling just fell over cause it was stretched out too much, and the stem was weak. put a small fan on them, and get more light on them. i propped my sprouts up with bobby pins when this happened to me (when i first started growing...not too long ago mind you). Also, I am going to suggest that you not water them every day, every second day would be fine, but make sure you water the entire container and not just around the sprout. If you only water right where the sprout is, the roots won't be encouraged to spread out to look for water. if you water the whole container, i think it would promote a better root system. Also, by watering everyday you run the risk of root rot or damping off (which someone mentioned in the other thread). If you are constantly keeping the stem of the plant wet, there is a really good chance it will rot and fall over. It doesn't look like this happened to yours as your plant still looks very much alive, but you were lucky. So keep your eye out for overwatering, k?
