Early on Hoya pottsii sp. Noid suffered from suspected root rot problems and rather than start it over at the time, I was hopeful it would eventually grow out of it.  This was the WRONG DECISION!  99% of the time it is better to take a cutting in a root rot situation and start the plant over again.  I have stuck it out with plants in the past, and once in a rare occasion it will pick up and re-root itself, but in the amount of times it takes, I could have re-started it and had a healthy plant in a fraction of the time.  I know that hope springs eternal, but it this case it shouldn’t! Below is a photo of the entire miserable plant after 64 months:
