I'm assuming your problem is in the hops. A couple of ideas. I'm new to this too and have no idea what I'm doing but there's a few things you can tweak. Use fewer hops. Use half a pack and save the rest so you can try another one with a pack and a half. Dry hop for a shorter time. Dry hop for a longer time. Do they bitter if you leave them longer? Dry hop at a different time. Has your wort hit FG when you hop? Add hops before your wort hits FG. Try adding hops after your wort has been at FG for a few days.
