spots on leaves
I noticed a few white aphids on the underside of my tropical hibiscus leaves so I sprayed the leaves on both sides with organic pesticide. 3 or 4 days later the leaves had these spots on them. There aren't any aphids on them but I have found an ant or two crawling on the plant.
What is this? Could the aphids have a delayed effect? Maybe the organic pesticide? Help?
