I have noticed that some of my pere's leaves are turning red and dropping off.
Is this a fungus? or a symptom of too much light or drop in temperature?
It seems to be passing on from plant to plant rather then popping up here and there,
that is why I have become a little concerned.


Cheers.

Going dormant ............... mine only have a couple of bright red leaves left.

Thanks Betty, sounds like I have to pump up the heat.

Just glad it is not a fungus.
