Growing Hoya Species Unknown aff. solaniflora

I received this Hoya as a small plant from Julie Kennedy in May of 2024. None of the plants in that shipment arrived in great shape, because of postal delays. The plant was rooted in coconut husk, but the leaves became very chlorotic after 3 months of growing so I took cuttings and started two more plants. Both the original plant and the two re-starts developed half yellow leaves. I suspected some kind of nutrient deficiency, but the strange thing was that none of my other plants had anything approaching this kind of chlorosis. Note the yellow leaves in the photo.
