Cryptos with yellow holes
I'm new to keeping Cryptos, Wendii (?)
in particular. I've noticed on a couple
plants a small yellow "hole" will appear.
Sometimes the hole will grow larger and
in a couple weeks, the leaf will die.
I'm wondering if anyone might lead
me towards a diagnosis.
I have mostly plants from the Americas: Swords,
Val, Sag, Baccopa, Cambia. Also some Anubas Nana
and others I can't spell. They are doing fine.
Thanks in Advance
