Upper leaf curling

[Kk2020]

Just turned 3 wks today.. a little concerned with curling of upper leaf and lighter coloration of upper leaves. Is this a deficiency issue of some sort or possible light distance. Any feedback would be appreciated. Thanks.

Tip claw smacks of N-toxicity, not sure about the red patch on the fan yet...
