My tomatoes seedlings are dropping and wilting, I used peat moss in tray. What could be the cause

Mwondha Faluku did you apply fertilizer there? Are you spraying it with fungicide?

Amindong Emos no I didn't spray any fertilizer nor any fungicide. I used peat moss .

E Mwondha Faluku if any thing is wrong it should be cost by that your peat moss thought I know nothing about it. Some documentery shows that peat moss is acidic and not a good choice.

Heat stress can cause this, once had a case like this, just shade the plant from extreme temperature
