How to kill an herb in less than a week!

OK, someone please tell me what I have done wrong to the Cilantro?

Too much water?

Too much sun?

Too little water?

Not enough sun?

I really thought I would have some fresh herbs this year on hand when cooking.

One day I decided to chalk board these little terracotta planters.

I thought herbs would be a perfect fill.

So far so good on the Basil, but as you can see..Cilantro, not so good.

 yellow?

Basil is doing OK, except I do see a bit of brown on the leaves, is this normal?

Well if nothing else, I sure made some cute chalk  pots!

Update 101:

 Cilantro is GONE!
What in the world did I do wrong?
