Leaf Question Newbie

QUESTION. My leaves on my plants are bending down a little on each side. My seedling have been under the lights for a week and half. I have just started to work some fox farm nutts into my water. Was wondering should I worry about the leaves, is there any solution etc.. First time grow all advice welcome

you shouldnt put nuets in till there about three or four weeks old. also depending on the light you want to have it fairly close to your plant
