I used Brewtarget software to scale the recipe to 17 litres in order to match my stove top setup.
While checking the recipe I found that I actually used 3kg Maris Otter and 1kg Extra Pale. I had previously forgotten about the Extra Pale.
Below is the scaled recipe with some hop substitutions. I couldn't find Ahtanum at that time and replaced with Willamette. Also, the scaled recipe called for 9 gr. of Amarillo and I though it's not worth buying a pack of Amarillo and use only 9gr. as I'm not planning to brew anything with Amarillo in the coming months. So I increased the Cascade instead of adding Amarillo.

I also tweaked a bit the bittering hops in order to limit the IBU to about 40 as I don't like the beer too bitter.
For the dry hopping I rounded up the hops to the nearest gram and where only a few pellets were left in the package, I added them too.
I bought one of
these for dry hopping and this beer was the first time I used it. Basically, just sanitised the mesh filter, put the hops in and submerged it in the fermenter 5 days after pitching the yeast. Then left it in for 7 days.
I wonder what do you mean when you said your dry hopping was not successful?
