All the new fronds that have grown so far have small holes in them, a variation of small white/yellow holes, and holes with brown edges towards the crown. Initially the first one that showed any abnormalities just had small translucent yellow spots and some small brown spots. But since then the newer leaves had small holes in them instead. Now theres four affected fronds. I suspect it's because I was overwatering the plant. Is there anything that I can do? Is it better to have removed the affected fronds in the earlier stage?
