Hi! This is my first time on this forum and I'm new to hoyas too. Though I'm used to taking care of many houseplants, my variegated hoya kerrii is giving me a hard time, so I hope there will be somebody to help, please.
I got a small variegated hoya kerri about 2 months ago (it was shipped). I repotted it in a small planter with just a mix of orchid barks and perlite for a substrate. And it quickly grew 2 new leaves (and 2 others are in the making).
But when the leaves opened, they turned out to look kind of curly. One is quite smaller than the other, and it has some dark spots on it. There are also dark little dots on some of the stems. I'm afraid it might be fungal.
The new leaves are also thinner than the other mature leaves, and they have no variegation (yet). As I'm new to hoyas, I'm wondering if this is normal. What do you think?
The plant is being grown indoors and gets medium to bright indirect light. The temperatures inside the house are around 77°F/80°F in the daytime, and the climate here is not humid.
I water my plant about once a week with pretty few water (I'm not about drowning my plants), and I don't mist it. I've also fertilized it once with a 4-3-6 watered-down liquid fertilizer.
I checked for pests but I haven't found any.
Do you think it's a fungal disease? I really want to save my hoya. I sometimes use a mixture of tea tree oil and bicarbonate in my vegetable garden when plants get fungal diseases, but I'm not sure about hoyas... I try to keep things the more natural and organic as possible.
I thought about repotting it but then I would have to water it, which might not help at all.
Does anyone have any advice for me, please? It would really help. Hoyas are too beautiful not to be saved.
Thank you so much in advance (and sorry for my English, I'm trying my best!).
