Does my bettas fin rot look like its in its healing stages?

Hello! This is my betta, qwerty who is a year old. Unfortunately I belive one of the plants started to rot and give him fin rot. I since got rid of those plants. Now this is the last day of anti biotics. His dorsal fin is the main issue, though it's not black it doesn't look that normal.
Water levels
Ph:7.3
Ammonia: .25 (just spiked when I found a dead nerrite last night) normally zero
Nitrite:0
Nitrate:10

Any tips or suggestions? Does he look like he's healthy or recovering from anyone's experience?
I will be doing a 50 percent change tomorrow since the snail died. I just couldn't change it until the antibiotics are done

 

I am personally terrible with finrot on crown tails(aleays think they have finrot) but i do see clear tips, which is usually a sign of healing and regrowth!

 

I attached another photo to show another angle

 

Really gotta say the fins/tail look pretty healthy

I know! His fins make me so paranoid even when he's healthy and always acting happy
