Have 2 Hoyas that are showing distress in some leaves.
One is H meliflua ssp fraterna and the other H verticillata/acuta.
They seem to be yellowing and drying out from the outside in.
Not sure why, roots seem fine, very potbound. Not overwatered
for sure. Could it be the cold ? I know we haven't been that cold but
we have had chilly nights for awhile now. They're definitely not used
to this much cool...

Thoughts ?
