OK some great feedback. It tastes like cheap lager. Something Carlsberg or Fosters, The WAG comment is interesting. I dont know what WAG is but i have read somewhere that some popular brands are oxidised and perhaps this is whats happening.
Also do the lagers i mentioned taste of sulphur? maybe thats why all my beers have it. its always the same water?
My most recent recipie is as follows:
2KG Marris otter
1.5g Citra @ 60mins
1.5g Simce @ 60mins
1.5g Citra @ 40mins
1.5g Simce @ 40mins
3g Citra @ 15mins
3g Simce @ 15mins
That made 9 Litres with start @ 1.052.
M44 yeast
After a week bottled it @ 1.013
The only time this was exposed to air after fermentation is when it eas being bottled.
With those hops, the beer should be an "in your face" IPA, but the majority of your hops are boiled too long. Also, the gravity is too low for an IPA, JA is right it should be 1.065 to 1.075, but boiling those hops that long should make it an unbalanced beer. Way too bitter for the amount of malt character, kind of an overly bittered, watered down IPA. Hoppy doesn't mean tongue splitting bitterness.
So without tasting it, we're all kind of guessing what's causing the beer to be so bland. I'm not convinced it's an oxidation problem, that makes the beer sweet and the beer tastes old and flabby, like a IPA from the liquor store that sat a room temperature for 3 months, yuck. Your hops may be old or of poor quality, I have had some hops that just plain suck, not very much aroma and low in flavor. But looking at your recipe, it appears to me that the hops are added to the boil too early, all those hops should be late additions, 5 to 0 minutes.
I would suggest to boast the hop flavor and aroma to bitter with Magnum to 30-40 IBU's and save all the Citra and Simcoe for the flame out or even better, a 20 minute whirlpool at 175F. Then dry hop with 1.5 ounces of either hop (or both). Simcoe and Citra hops are too nice to be used as a bittering hop, boiling hops will reduce the hop flavor/aroma. The flame out or whirlpool addition will bring the bitterness up to 55-70 IBU's.
Personally, I rarely add any hops to the boil when I make an IPA or Pale Ale, I add them to at 175F for 20 minutes and they turn out awesome.
Sulphur in beer is very subtle, blends into the background, adds to the complexity of the malt and makes the beer crisp on the finish. A lot of people miss it and it's very common in German lagers.
Don't fret water at this point, you got work on flavor and aroma. Water modifications affect more the bitterness character than the hop flavor. Higher sulfates sharpen bitterness and have a small affect on drying the beer out. I have brewed some great IPA's/PA's with a chloride to sulfate ratio of 1:1. Case and point are NEIPA's that have a higher chloride content to soften the bitterness. The last point would be to use soft water for brewing to keep the bitterness smooth. A high finish pH will make the bitterness sharp and harsh.
Sorry, this is a little like drinking from a fire hose, but it will get better the more you brew these styles. Practice make perfect.
