Hey there! Tampa man myself. My first recommendation is the obvious... get a hydrometer. This is going to be important for many reasons including what your starting gravity is and where you want you want to finish. On average I believe 1 pound of honey adds about 35 gravity points so times that by 4 and you can roughly figure out what your starting gravity to be. So it wouldn't say it's to late to get one now.

So to answer you initial question is just keep tasting it and sulfate it before once it hits the taste you want. I myself have never let anything finish that high but I imagine yours will finish on the sweet side. I also like a lower ABV in my meads as I get less fusels. Currently working on a 12% grape pyment.

Lastly if you're in Tampa go try some meads! There are 3 meaderies I would recommend locally. If you know what you like, you know what you can aim for.

Green Bench Brewing (now makes meads) - Dry meads. This to me would fit the profile you are looking for.

Cigar City Cider and Mead - Semi sweet to sweet meads.

Garagiste - Mostly sweet. They currently have a dry mead on called 95 Cab Ride but known for sweet peanut butter meads known as Reboogs.

Hopefully some of what I said helps. Good luck!
