For $0< p< \infty $ the Bergman space$A^p_\mu $ is the collection of functions in $L^p(\mu )$ holomorphic on $\Delta $. We show that whenever a Gaussian power series $f(z) = \Sigma \zeta _na_nz^n$ almost surely lies in $A^p_\mu $ but not in $\bigcup _{q>p} A^p_\mu $, then almost surely: a) the zero set $Z(f)$ of $f$ is not contained in any $A^q_\mu $ zero set ($q>p$, and b) $Z(f+1)\cup Z(f-1)$ is not contained in any $A^q_\mu $ zero set.
