I started these bean plants about a week ago. They sprouted quickly and looked pretty good. Then after about a week I noticed they started to point their leaves down towards the dirt instead of at 90 degrees to catch light.

I keep it between 75 and 80 in the house ( I am starting indoors as it has been raining cloudy and light would have been an issue). I have them under two 4' fluorescent for about 14-16 hours a day. They are bout 2-4 inches below the light as of current.

I am watering 2-3 times a day with spray bottle making sure to be careful not to spray the leaves. I'm not sure why they are curling and drooping but was wondering if anyone could tell through a picture or with my description of what I am doing wrong.
