Thank you both for your input. I'll just be a bit more careful next time I give it fertilizer

Could be a Buddleia leaf weevil, Cleopus japonicus, considered to be a bioloogical control for the invasiveness of butterfly bushes, particularly in NZ and Australia where the plants are noxious weeds. I am not aware of them being very common in the US but perhaps they are being employed for the same purpose (Buddleia is an invasive species on the west coast and beginning to become one in other areas). And the only garden weevil I am aware of that can fly!

I'm a newbie to growing roses, and have a lot yet to learn. I took the advice from the Gardener as good. You provided great alternatives I need to review. Thank you for this information. It's interesting most of the roses with rust and downy mildew problems were shipped in from other states, but a few were from in state. As for Rose issues in Florida, I must be a magnet in attracting them. I had 3 Rose plants die mysteriously in April, less than 2 weeks after buying them as healthy plants with lush, abundant foliage. No bug infection detected, watered properly on occasion, great all day sun position. So issues are no longer a surprise for me when they appear.

My rubber tree tineke that I ordered online looked fine the day it arrived and I immediately transplanted it to a new pot with drain holes. I did not watered as I want the plant to settle first on its new environment.A day after, I watered it thoroughly and misted the leaves. Then I saw a small brown spot near the leaf tip. As the days went by, the browning spread further and when I checked on the leaf underside, there are some grayish things underneath. They are circular and seem to be wet and oozing out from the leaf.I've attached a photo of the leaf in the comments below.Can you tell me what are those thingsunderneath the leaf? Is it some sort of fungi or bacteria that I should be worried about?Please give me advice on how to deal with it as I really want to grow the plant.
