Just planted this Creole tomato plant on Sunday and is now starting to have brown spots! Any ideas on what is going on?

I live in New Orleans and planted this Creole tomato plant in a pot on Sunday. It is a new pot with new potting soil. I have watered it every night since getting it. I have two other tomato plants of different varieties that look fine. Any idea on how to treat this? I dont see any bugs or critters, ive been looking. Seems the brown spots just turned up today.
