BigBill said:There is nothing wrong from what I see. Hoyas are not particularly fast growing plants. I have the exact plant and mine likes to grow dry. Too much moisture makes them unhappy.
When the plant is happy it makes lots of new shoots with tiny leaves. Those leaves expand very slowly.
Hoyas do not need a lot of light. Just make sure that the pot it is in has drainage holes. I water mine about once every two to three weeks.
And you may have discovered the problem with growing plants, moisture meters!!!! They are terribly inaccurate and in my mind useless! I suggest that if you want to learn how to grow plants, a moisture meter is not the way to go.
BigBill said:Listen Alba, all you need to do is water it well every two weeks and see how things go. If you forget and it's three weeks, it will be okay.
But every time you lift that plant you will learn what it feels like after watering and when it is dry. Over time you will know just by picking it up.
Yes they lose leaves which is no big deal. Put Hoyas are really easy to grow. Just as long as they are not over watered. Plus don't give them too much sun.
You will catch on. It is a really nice plant.
BigBill said:Well everyone will have an opinion on how to grow them but years ago I learned how to grow these guys. I gave them way too much water.
You're welcome!

Your Krimson Queen Hoya (Hoya carnosa 'Tricolor') is very pretty. Yellowing leaves can be a sign of both over watering and under watering. I've been growing Hoyas (and many other tropical plants) for 54 years now but I've never used a moisture meter because I've read many times that they are quite unreliable at detecting proper soil moisture.
About 16 years ago, I learned from a Hoya nursery in Hawaii that a good potting medium for these types of plants is a combination of potting soil, with lots of chunky matter mixed in. I always add lots of orchid bark mix, perlite, or coconut husk chips to potting soil for all of my Hoyas and other plants. Some people add Leca (clay pebbles) to the soil, as an alternative to the bark. This type of potting mix prevents root suffocation and rot by allowing for excellent aeration at root level and aiding in proper drainage. This type of potting media dries out much, much faster than using a dense potting soil alone but it sure helps greatly in preventing root issues.
All of that being said, I wouldn't suggest repotting a possibly already stressed plant. If you can determine that over watering was the issue, just allow the soil to dry for longer periods and if you can determine that the soil was not getting moistened at root level, water thoroughly and wait until the top 1 to 2 inches of soil feels dry before adding more water. The key is to try to keep the soil barely moist, not too wet and never allowing it to remain totally dry for long.
With moisture meters being so unreliable, it's difficult to know if your plant is staying too wet, or too dry but if new leaves have dried out and dropped, I'm leaning towards lack of sufficient moisture. When you water, remove the plant from the decorative hanging container, pour water atop the soil until it's freely exiting the drainage holes. Allow the plant to sit out and drain for awhile; never allow water to remain in the bottom of the pretty outer pot.
Again, Welcome and please keep us posted on how your plant is doing! Also, you may like to check our our Hoya Forum where those of us who grow these great plants like to chat about and share photos about our plants. The Hoya Forum can be accessed here: https://garden.org/forums/view...

The leaf on the right and it's petiole look okay. The stem in the center without leaves is dead.
The main plant stem isn't black like I usually see with rot and the feeder roots look good. Does the stem feel firm when gently squeezed? If it feels soft or has any give when you squeeze it, there may be a fungal issue.
I'd be concerned about the nursery pot sitting down inside that pretty hanging planter because it may block proper air circulation which will definitely cause problems. Hoyas need really, really good air circulation at root level for the plant to remain healthy and thrive.
