Jasmine Sambac Help! Something Is Wrong With My Jasmine Sambac!?

Help! something is wrong with my jasmine sambac!? - jasmine sambac

We had the works for some time. I noticed that the leaves curling, so I thought, hey may have aphids on the plant. Therefore, malathion used syringes. Flowers worked, there was again a lot. recently, I noticed the same thing that happens! Not aphids may not be new, right? I do not see an error or white residue. It is as if there is anything that affects the life of the new leaves and flowers in full bloom prevented! tries, vinegar and chili powder and a little work. but now the leaves are folded.

Please help!

** The plants are really out to get full sun, water, etc.
