The tips of the leaves on both are developing dark spots so I've taken them off as I see them. I last thoroughly watered a week ago. It's autumn here now but we've experienced warmer than expected temperatures that's are between 18-24 celcius(Auckland New Zealand). And they're in a good spot to get sun and I also take them outdoors often. Should I stop watering now and just let the leaves fall off naturally? Are the brown spots normal for this time of year?
