How do you get a G-max Urshifu?

Question

I did the tower of darkness and got my single-strike urshifu but I can't feed him max soup and when I talk to mustard on the couch he says "the next step can wait till Ryder does what he needs to do" and I think that means something about getting a g-max urshifu

Answer 1

First, you have to finish the game in the mainland, Galar, not the Isle of Armor. After you beat the main-game, Go back to to the Isle of Armor inside the Master Dojo. You will find Hop there. Walk up to him and get into a cutscene. When it is done, you go on a quest with Hop to find honey to help Urshifu G-max. You have to go in the Forest of Focus looking for Pokemon with Hop. Eventually, you realize you need to find a Vespiquen. You ride your water bike northwest of the Tower of Waters, find Hop there on a Honeycomb shaped island, do a accidental Max Raid, and get the Max Honey after you defeat the Raid. After that, collect at least 3 Max Mushrooms, go back to the Master Dojo and talk to the guy who makes Max Soup, then give it to Urshifu. This will allow Urshifu to G-max.

Answer 2

You need Max Honey.
You can find hop in the Forest of Focus, and I won’t spoil the things you have to do with him to get the Max Honey. Urshifu only eats the Max Soup if Max Honey is mixed in to it.
