You cannot judge your beer based on what the unfermented wort tastes like. If you ferment it, bottle it, carb it up, and chill it and it still tastes like soap, then you should be concerned.
Unfermented wort, especially from an IPA is going to taste even more bitter than you expect, despite all the sugar, so that's probably what you're tasting combined with a fair amount of vegetable matter. Unfermented IPA wort tastes weird- I think you're fine.
