My friend has just acquired this beautiful Anthurium wendlingeri for me!
Sadly it had some scales and mealy bugs, which I’ve already washed off… but there is also this very strange damage:
What kind of disease could this be? Fungus, bacterial damage, a virus, a fertilizer incident or just cold damage?
Should I cut the diseased leaves off? (They also happen to be the oldest…)
Should I isolate the plant?
Please help me, every information is highly appreciated!
For reference, a healthy specimen of Anthurium wendlungeri:
