I was trying to talk myself out of it more likely.@Kevinaxx you have a beautiful hoya there. Nothing wrong with it imo. Many would love to have white leaves like that. If the leaves are firm and fleshy and can't be 'folded', it isn't dehydrated.
The smaller leaves on the end appear to be new foliage which is growing.

Tri-coloured hoya! Also been eyeing on them. I hear their flowers are lovely and smells wonderful! Yours look very lovely.
