Hoya nerds! Just got a Hoya acuta (aka verticillata) albomarginata from online seller. See pics. Leaves vary from seemingly unaffected to severely. Black spots are in the plant tissue, and cannot be wiped away. Plant seems generally heathy overall. Any ideas what might cause this? Ordered with two other Hoyas (diff species) that appear unaffected as well.
