A canonical variable coefficient nonlinear Schrodinger equation with a four-dimensional symmetry group containing SL(2,) group as a subgroup is considered. This typical invariance is then used to transform by a symmetry transformation a known solution that can be derived by truncating its Painleve expansion and study blow-ups of these solutions in the L-p-norm for p>2, L-norm and in the sense of distributions.
