Hello.
If you are diagnosed as having Schizophrenia, the incidence of pot smoking does not seem to have caused it. Cannabis (Pot) is however, known to induce psychosis, which could have a presentation similar to Schizophrenia. Hence, you may need to discuss this issue with your doctor again.
Schizophrenia is known to have a genetic predisposition. And there are no substances or foods that might cause it.

Take care.
