I'm having problems with my H. heuschkeliana is devolving yellow leaves and some have brown spots (see pic's) I let all my Hoya plants dry out between watering but they are still watered every 4-5 days as they dry out quickly. I have many other starts about the same size and all are doing great but this one plant. They are under T5HO lighting.

Given the size of the plant relative to the size of the pot and the apparent soil mix, I would be very surprised if it needs water more than weekly. Allow at least the top quarter of the soil (not just the soil surface) to dry between waterings.

I have learned that heuschkeliana likes to be kept on the moist side. It's only been a week but more water was greened up the plant, of course nothing can be done about the damaged already done. It looks better, I'll see how it looks after a month or so and report back.

Steve, the brown coloration on the leaves of your Hoya (Hoya heuschkeliana) may just be from high light levels but the yellowing on the other leaves appears to be from over-watering. I've never found H. heuschkeliana to be happier by being kept on the wet side but I live in Florida where we have extreme humidity so my plants receive a lot of moisture from the humid air.

I had a decent size H. heuschkeliana until about 8 years ago when it was left outside and a winter freeze killed it. I obtained a very small plant in the summer of 2015 and it's still in the tiny pot that it came in but I added more perlite to the soil when I got it. This little plant has bloomed three times in the past 1 1/2 years. It stays outside most of the time but I moved it to the kitchen counter a couple of weeks ago so I could enjoy the evening fragrance from those tiny flowers. I will move it back outside once it stops blooming. I grow everything in a chunky, fast draining potting medium. I only water it every 2-3 weeks when it's indoors and even less when it's outside.
