Yellow tips problem

Ok so i got these seedlings and the bottom leaves are turning yellow and crunchy.

They still grow though.

I have narrowed it down to either nutrient burn from overwattering (not letting soil dry out) or Nitrogen difficiency.

I am using just standerd bagged soil from the garden shop in my neighbourhoud.

Can anyone shed some insight on what this is?

Grtz

Light ferts watering wind - one can only guess. Is that a temp probe in direct light too?

guessing by your question, this is not done? i keep it at the level the plants are, wich i thought was logical? Cant put in the shade as there is none?

just as a follow up message, they seem to have outgrown the problem. I put the cause on the soil being too "hot".
