His Q does the same amount of damage no matter how many enemies it hits. Minion's health increases over the course of the game, so the same ability won't always kill the next wave of minions in one hit.

I've experienced this many times in early/mid game as Gragas, where I was just barely one shotting the last wave but couldnt pull it off for the next one. As long as you are doing well you should quickly outscale the minions and go back to one shotting them
