In this paper, we extend our earlier unique continuation results \cite{ PZ2} for the Schr\"odinger-type inequality $ |\bar\partial u| \le V|u|$ on a domain in $\mathbb C^n$ by removing the smoothness assumption on solutions $u = (u_1, \ldots, u_N)$. More specifically, we establish the unique continuation property for $W_{ loc}^{ 1,1}$ solutions when the potential $V\in L_{ loc}^p $, $ p>2n$; and for $W_{ loc}^{ 1,2n+\epsilon}$ solutions when $V\in L_{ loc}^{ 2n}$ with $N=1$ or $n = 2$. Although the unique continuation property fails in general if $V\in L_{ loc}^{ p}, p<2n$, we show that the property still holds for $W_{ loc}^{ 1,1}$ solutions when $V $ is a small constant multiple of $ \frac{ 1}{ |z|}$.
