Hario V60 02: this tastes like lemon peel and regret

[Okra]

Brewer and filter: Hario V60 02 plastic; Hario tabbed 02 paper
Grinder, burr and calibration: Baratza Encore ESP; M2 conical burr; setting 24; internal calibration middle
Bean, roaster, process and roast date: Ethiopia Chelbesa; Tim Wendelboe; washed; roast date 2026-08-21
Dose and water mass: 18.0 g coffee; 288 g water
Temperature and water profile: 92°C; Brita-filtered tap water, about 110 ppm TDS
Pour/agitation schedule: 54 g bloom for 45 s, then two even pours to 288 g; one gentle swirl
Drawdown time: 3:05
Expected and perceived flavour: expected berry sweetness; perceived cup is sharp at first and hollow as it cools
Changes already tested: tested one brew with remineralized water while keeping the recipe fixed

I had this working two brews ago and now I am getting the problem in the title. I wrote the numbers down because otherwise I know we will spend ten replies discovering I changed three things at once. What would you change first?

I tested one change from the opening post and it moved the cup, but did not finish the job. Next variable: increase dose by 0.5 g while keeping water fixed. Why: the present agitation can be creating fines migration and choking the bed. Expected result: slightly more body without making the cup muddier. I will report the actual result rather than stack another change on top.
