Parts of my plant is dying off what to do?

I brought 2 jasmine plants from a nearby farm.
i put them in the same pot.
one of them was not upright and was shaking from the wind, so i put a wooden stick support and tied it with a cotton yarn.
i’ve had them for almost a month now.
i dealt with a couple of white spiders and some caterpillars.

now i am having a problems again:
1- the stem of the one that put support for, is turning scaly white.
2- some leaves are being eaten but i find no spiders or caterpillars.
3- the edges and tips of some leaves are turning brown/burnt.
4- flowers are blooming and stays like that for few days then either slight browns and falls or just falls.

i added some pictures of the stem and some parts

BTW i’m in Alexandria, Egypt humidity is 60%~70% temperature is 33C (91F),
my house is right in front of the shore so i get some strong wind.
i leave the plant from dawn till noon in direct sun light when sun is too hot i move it into the garage
