We reconsider the evolution equations for multigluon correlators derived by Jalilian-Marian, Kovner, and Weigert. We show how to derive these equations directly in terms of vector potentials (or color field strength) avoiding the introduction of the concept of color charge density in the intermediate steps. The two step procedure of deriving the evolution of the charge density correlators followed by the solution of classical equations for the vector potentials is shown to be consistent with direct derivation of evolution for vector potentials. In the process we correct some computational errors of Jalilian-Marian, Kovner, and Weigert and present the corrected evolution equations which have a somewhat simpler appearance.
