Pink Anthurium in apartment - leaves turning brown and dying

Question

I've been keeping 3 plants of pink anthurium in my apartment - bought at different points of time from different shops, all plants initially healthy. All three however end up showing the same symptoms: leaves start turning brown at the tip, eventually killing the leaf. The plant themselves sprout new leaves but quite slowly, with a lot of "stumps." Moreover, some young leaves already have brown tips (see photos).

I try to water them once or twice weekly (although I tried changing the regime and doing it once weekly) and spray them every 2-3 days but it doesn't seem to help.

One more data point: the apartment doesn't get a lot of sunlight.

Am I treating the plants wrong? Please help!

Answer 1

This is difficult to say as some of the more obvious problems are not apparent:

• I don't see any sign of scale or thrip
• the portions of the leave that are browning do not look like they have a fungus or virus
• no signs of nutritional deficiency

I suggest that over watering might be the cause.

• provide more light
• ensure good drainage
• water thoroughly and let the top inch of the medium dry

Answer 2

As far as I know, Brown tips like that are caused by the oils from people or animals touching them. If you have animals, move them out of reach, and if you handle the leaves a lot, stop.
