Need some questions answered about seedlings.

I am starting from seed for the first time as I have always used clones.My seedlings are a week and a half old and they are in containers and are about 2 inches tall.Can someone tell me how often I should water,when should I start feeding them nutes,and is 24 hours of lighting ok for them at this stage?Any input would be greatly appreciated!Thanx.

Bro how many posts did you make today? o.o
you could have asked all this in one post.

But watering. you need to keep the soil moist. not soaking wet.. moist.
and yes 24/0 is fine for them at that stage. youll want start to give them
lights off sometime soon.
