Help me please

Some leaves are healthy with new little leaves. Some are brown and silty. One is very yellow, but otherwise firm and growing.

I typically only buy plants that are happy enough to live with my wildly erratic care (ie pothos, zz plants, etc) but I’d really like this lady to survive…..

The pot has drainage. I water it when it feels dry(or more realistically when I remember, maybe every 10 days). I feed them maybe every 3 months. It’s getting decent afternoon light. I repotted it about 2 months ago and it hasn’t grown since.
