I would be very gratefull if someone could help me identify the reason for these problems.
This is a croton. A few weeks ago it had some aphids and I got rid of them using an insecticide. Now I noticed these spots on the leaves. They spread quickly and then the leaves fall off. The plant is not overwatered and hasn't been fertilized soon because of the treatment.
The same, or at least they look like it, spots were on the leaves of these avocado trees and in just a few days the fell off and now this is what is left.
I noticed these tine black spots that are a little bit protuberant. They are on the back on the Hibiscus leaves. This plant also had aphids and was treated with the same insecticide.
These black spots I noticed on the new leaves of the fiddle-leaf fig. It isn't overwated, has been fertilized with a special fertilizer in the dosage written on the bottle. The leaves fell off.
Also today I noticed that the Hoya I have is droopy and the leaves are soft. It is near the croton plant.
Please if you can help with at least some of these problems, write some suggestions. I really don't want the to die.
