Yes, Camping is right. You're really going to have some big hop presence in this recipe as-is. 1/2oz of Magnum @60mins is too much bitterness for a hefe. Sure you can use em but a hefe only has between 8-15IBUs, and an american wheat upwards of 30IBUs, so you'll have to scale back a bit there. If you are shooting for an American-style hefe, then why not go with some american hops? Maybe bitter with Willamette @60min and some cascade @15. Skip the aroma addition... Now you can do whatever you want here, after all it's YOUR beer, but FWIW a wheat beer should have about 50% wheat in the grist. And make sure you use a blowoff tube - hefe yeast can be quite ferocious
Cheers
