It would help if you uploaded or shared the recipe for us to look at but pale lagers such as Bud and Bud light typically use corn to up the gravity and increase the alcohol while keeping the color and body light. I currently have flaked corn in my pantry for a cream ale I'm doing in January or February. Seems like your recipe is skipping mashing any corn and just adding straight corn sugar. Should work fine. I'd just treat it as you would DME, add it at any point after the mash (if all grain) and before the boil
