Buckinghamshire, United Kingdom

Can anyone tell me, please why my Anthurium leaves keep turning brown? It’s not overwatered nor is it too dry. It lives on a north facing windowsill.
Spring last year I repotted it, taking three little attachments from it. Two died, one looks very healthy but the mother plant isn’t doing well. If I was fanciful I’d say she was grieving for her babies! Whatever,I’m at a loss to know what to do because it’s always flowered well.
Help please!
