I have violated pti probation in Florida two times now... what will happen? Will be put on felony probation?

You will be on "felony" probation if the crime you did was a felony.
So was it?

Also what did you do to violate your probation, rob a bank, get drunk, use drugs or what?

But it is possible, that what ever probation you were given, you could go to jail for that amount of time instead.

It depends on the charge and how serious was the new charge. If it was a technical violation you maybe reinstated. Was it a new charge?
