I dont see there being a problem with that, although the strength difference between hydro nutes and soil nutes would have to be addressed, chances are though that the hydro shop will do a great soil nutrient. Ask them what they have.
Everyone here seams to love foxfarms so if you can get that go with it. Earth juice is good too and its organic which will make your weed taste nicer, if you can get that get then everything be super duper apart from the stink of shit that it leaves. Earth juice = stinky shit smell.
