Leaves curled my 9 day old plant

A lot of times you just get some weird genetics in the first few sets of leaves. Overwatering or have pre-fert soil could also result in some nute burn and cause this. Your fan shouldnt blow directly on the plant, otherwise it's good. These leaves arent likely to self-correct and will probably remain weird looking as they grow into fan leaves. Don't let that worry you, you probably will have already fixed the problem at that point so dont keep trying to fix it.
