92 grams of gypsum is way over the top. Start with maybe a gram per gallon.

You've still got a boatload of calcium and sulfate in there. Why the MgS04?

It looks like you're using all RO water for the mash, and then a mix of tap water/RO water for the sparge?

I like the looks of your water "plain" better than the one with the additions.

The water profiles I've seen for ESBs have been around 300ppm Ca, and 700ppm SO4. I was under the impression I was using a much toned down version at ~100Ca and 300 SO3

I adjusted the water to 100% RO for mash, and 34% for sparge.

At first sight, it looked terrible but when I divided by 3 to approximate to my 5g batches, it looked much better but more attuned to an IPA.
In Pale Ales, Terry Foster recommends Ca 50 - 100 ppm, SO4 100 - 200 ppm, and Cl 20 ppm for a beer like an ESB.
I like his recommendations.
I'd cut back a bit on the gypsum, and eliminate the epsom salts. (From everything I have read, you can ignore the minimum Mg requirements as the malt itself contains sufficient Mg. (George fix, and AJ Delange)).

-a.
