You got clawing going on and leaf growth surfaces are rough/sharp. Poke a moisture meter around and I'm betting you find the soil is good but your root ball is holding on to too much water. Note - poking around that wet root ball will also help open up some aeration. You might need to wait for it to complain for water before giving it some for a couple weeks and let it get some more oxygen. If it worsens, peroxide might help. It'll help the plant fight off Pythium. To prevent it, when you have confirmed it's time to water again, start doing your watering around the outer rim of the pot and don't put any water near the base.
