That's why 90% of natural bodybuilders don't go to failure. Heavy or not. I can do 405 x 2 flat bench on Monday, do 225 x 3 standing military press on Wedneday, then do some heavy ass inclines on Friday.
Working your muscles once per week is one of the worst ways to train. Think about it.. If protein synthesis is only elevated for 3 days within the muscle, why in the world would you want to grow for 3 days, then struggle to maintain your growth for the other 4?? Soreness is not an indicator for growth, and you can certainly train while sore.
