Thanks for the info, very interesting!
I was wondering if it should be repotted when I pulled it out yesterday, so I will do that.
Regarding watering do you have a recommendation? As everyone was suggesting it was over watered we let the soil dry out a fair bit between each water but I'm wondering if it's just been too dry the whole time. Humidity is quite low here at this time of year (<30% often) and despite having humidifiers running quite a lot, I expect it also dries out quite fast.
My moisture meter shows it to be pretty dry right to the centre, 5 or 6 days after the last water.
