I'm going to guess that you are overwatering the plants. Generally speaking, bagged potting soil doesn't drain well and you are giving those plants quite a bit of water.

On another note, I think it's a little late to be planting tomatoes and peppers even in sw fla.

Oh I am using a potting mix, not a soil, and it has plenty of vermiculite. The home depot garden guru said these can be planted all year round in florida.
Another thing, when I took the plant from its original container it was in good shape. When planted it in the mix, this is when it happened. Do you think it's possible that there was too much fertilizer in the mix?
