Not really. Although acid will change slightly during fermentation; some
acids are generated by the process, others reduced - with the nett effect
(usually) of a slight rise in pH. MLF will certainly raise pH. As it
changes, you may want to adjust acid, even if only slightly, depending on
starting point, change, taste, and desired style.
