Its prob what yooper said, under bittering. Had a similar issue with a 2 hearted clone. was using whole hops for the first time and used my hop spider. should have just threw it into the boil without the sipder and upped the hops. was hoppy but bitterness wasnt there and tasted sweet even though the FG wasnt that high.
i dont think citra hops makes the beer sweet. it does give it a nice passionfruit flavor and aroma which i love. my citra / mosiac ipa is awesome and not sweet at all... smells like a tropical fruit orgy
