Leafs

Just started growing my new plants and they are about 4-5 days old and the (Future 5 bladed leaf) is curling at the bottom, its like shrivelling and drooping down. What could the causes of this be, I have been giving it good amounts of water and heat and also I have a fan on the plant, I don't see what I'm doing wrong.

Pic's would be nice

Probably too much water and too much heat!?

Weed likes to dry out between watering, and it doesn't usually like to grow in places much hotter than people do i.e. room temperature. Over-watering is probably the most common mistake for the inexperienced.

Ok thanks and I'll try upload some

They are curling at the bottom of the leaf and it is brown
