Might be something to do with minerals in your soil or irrigation water - otherwise you haven't given enough information for anyone here to be able to tell. Plants can go yellow just from being kept too wet.

might have a lot to do with planting in july in FL ...

how were they planted.. and how have you been watering them ..

one thing for sure.. they are stressed ...

and it must be severe stress .. if leaves turned yellow in 10 days ...

take a hand trowel.. and find out if there is any moisture down 3 to 6 inches.. where the roots are ... both on the gob planted.. and in close surrounding soil ....if you are relying on lawn irrigation.. that is probably the problem ...

in my MI... i dont plant ANYTHING in july or august... maybe pensicola is different ...

how about a pic or two.. so we can see size.. color.. etc ...

Might be transplant shock. A picture or 2 would be helpful.
