Issues With Surface Roughness Castable and Castable Wax

What could be causing this surface roughness on my castings? I’m currently using the new castable wax resin from formlabs, but it also happened with their regular castable resin. I’m using their recommended burnout schedule and r&r plasticast investment. Any tips or advice would be really appreciated. I’m pulling my hair out over here. [smaller]
