What deficiency/problem is this?

Brown roots? Problem unless what you have in the tank is naturally staining. pH - is it stable? EC/PPM?
I think it's naturally staining. I've had root rot on the plant beside this one and can noticeably see a difference. Ph has fluctuated in the past week or so when I was out of town, but is stable now at 6.1. I don't know the ec/pmm.
