Kerrii is easily overwatered. You should let it dry good between waterings. It's a very succulent Hoya that can take beieng too dry better than being a little too wet. It also needs a very loose mix, and not to be overpotted, all things that will aid in correct watering.

Thanks Denise. It's in a great soil as I purchased it from Ric. The leaves are not yellowing they're just getting this streaking on quite a few of them.

It could be virused. There would be no solution, if so.
