thanks so much!!
I got this Alocasia Calidora from Trader Joe's last weekend and noticed this white, crust-like substance behind the stems of about half of its leaves. I've checked it for pests and haven't seen anything. It did come with some yellow dots were something may have sucked on its leaves, but I haven't noticed any new spots since I got it. I've tried to remove the white crust with a toothpick, but couldn't really get any off. It's quite hard and only appears on two out of five leaves. Did some google searches, but no luck – any idea what this substance could be?
