Hello everyone!

This is my first post here. I'm not very experienced with hoyas, but I've had this plant for 3 years and I love it and dread something happening to it!

This is the overall look of the plant.
First off, are these white spots normal? I think it has had them since I moved it indoors a couple of years ago.

Recently I've noticed that after a couple of years of doing great on top of my fridge, it has stopped growing new leaves. Also, some vines seem to have dried out at the tip, and now on one of them the leaves are gradually yellowing, from the tip going up.
I just read that the vines shouldn't be growing downward, so I guess that could be the cause?

Here is the last part of the vine that I cut off

Here's another vine, dried out and with slightly yellower leaves at the tip.

In addition, some leaves are curly like this one

Finally, I just took the plant outside for a shower, and noticed these black spots underneath some leaves =\

Can someone tell me what's wrong with it?

Note that I live in Greece, so the temperatures can get up to 30-35°C indoors.
I keep the plant in a pretty well-lit north facing room.
I water once every 1-2 weeks in the summer (generally keep it on the dry side cause I almost lost it to overwatering in the past), and occasionally fertilize with an all purpose liquid fertilizer N-P-K 6-5-6 for green plants.

I believe that your Hoya problems are due to excess temps and inadequate light. Try to keep temps below 27 C. Hoyas need lots of direct indoor sunlight, which you are unlikely to get on top of the fridge. At a minimum, it would have to be right on the windowsill of a north window.

The white spots are normal.
