Sharp White Leaf Spots?
I found this on two (#1 & #2) of my Amaryllis leaves today. I thought it was dust but it doesn't rub off. Nine days ago I transferred the plant to a new pot for drainage without adding new soil. Two days ago I fertilized with my usual liquid (1/4 tsp/gal Jack's). It's not on all the leaves and it appears to be mainly at the tips.
