Plant is not doing well

[Kutor]

Leaves are getting more and more yellow, and at the end they fall of.
I could not take the pic of the plant, but here is the pic of the leaf

I hope someone can help, thanks in advance.

But more likely it has multiple issues because it isnt getting a good balanced fert....
