Brown tips and Brown spot on top of seedling leaf.. Help

My seedling is about 2 weeks old and for two days ago the tips started to get a little Brown on the tips and today a pretty big Brown spot appeared.. Anybody know what it might be?

What are you feeding them?

Hi @budman111
Havent fed anything yet, been afraid of root burn..
Shouldnt you wait a few weeks until feeding?

What kind of soil?
I use happy frog and sometimes it is too strong for some seedlings and they look like that.
They always turn out fine.

I use an organic pottingsoil from a local store, thought it was nutrition free, but it was not... i bought a few bags of it.. And couldnt return it back. Would you recomend switching soil? Or Just keep it?
Mixed it with perlite

Thanks for answers guys
