Betta fish fin issues

[Brittm1228]

Hey! I’ve noticed recently my twin tail betta fish has been having issues with his fins. They look awful. I’m trying everything I can to help.
I recently did a complete water change and added new live plants. The test strips say everything is where it should be. It’s been probably a week since I did that. I’m waiting to see if it helps his fins. I haven’t noticed anything different as of yet.
I tried the betta fin rot liquid for a week as recommended but it did nothing. I haven’t tried aquarium salt but I’ve heard that could be a solution.

Here are some pics of him today, he seems happy and energetic but his fins are just so sad looking
Any info or recommendations would be awesome.

The two plants on the left are live and the other plant looking things are soft and squishy texture.
