When you try to think to Transitions from Prequal to the Original trilogy there are a lot of holes that need to be explaining
How long did the Empire use clones as part of their army? There has to be some transition from using close to normal everyday humans. Be rather weird if there were clone troopers in the OT that had served during the clone wars.
The problem with a clone army is that except for upper echelon commanders there would be no need for recruits into the Imperial Forces when you can jsut pull them out of a cloning chamber.
I can only think that sometime during the 20 years between RotS and ANH that Kamino's gave up or were destroyed by the Empire
