Weak flavor in my beers

[Dovage]

I've been brewing for a while now. Almost 10 years now,sheesh. Time flies. Half of that was in S Florida where apparently the tap water is great for brewing. I always made decent beer. Moved to Wisconsin and my tap water sucks, took me a while to figure that out .
So now I build my brewing water starting from RO. Long story longer, the flavors in my beer are great. My last couple, a Brown Ale and a Dunkelweizen tasted how I hoped but not strong Enough. Very muted but not watery. It's been this way for my last handful of batches. Flavor good and clean but at a 4 when I was hoping for an 8. I do BIAB in an Anvil Foundry. Should I boil longer and put a bit less into the fermenter?

If you're not hitting your original gravity, that would be a way to get it.

The two batches you mention as underwhelming are malty. How's your chloride levels? Sodium?

Weirdly I am hitting my OG, or near enough. As for the salts Ive been using the basic chart that came with my Foundry. Do you have a general amount in grams that you use?

Anything change with how your grain is milled?

On a totally different tack, have you recently recovered from COVID?

Sounds like classic oxidation to me

Oxidation can come across as dull malt flavor rather than cardboard as you'll typically see described

No change with how the grain is milled. I do it myself always same settings.

How recent is recent? Probably 6-8 months ago I had Covid.

Might be a possibility. I don't do closed transfers when I keg.

How long have you noticed the flavor change? Could it be your sense of taste hasn’t fully come back?
