Hello, I got two hibiscus last year around the same time (maybe a month or two apart) this summer. They seemed to be doing well (lots of new leaves and nice glossy leaves) but now that the seasons are changing I’ve noticed they aren’t as happy. They are near a vent but in the summer when cool air would have been blowing on them they were okay so I figured warm air would be too. My bigger one has been getting yellow leaves left and right and is super droopy and sad, the smaller one isn’t as bad but is still not at its peak (the smaller one is closer to the vent and only a little higher, although as far as I can tell they are both getting the same amount of sun) Ive never gotten flowers from either but I figured that was just because they are inside and my room is pretty cold, however now that it’s warming up they seem to be doing worse. The picture is of the worse of the two but my camera can’t seem to pick up it’s droopiness I guess lol
