Hello everyone! I have my dear tetrasperma on a trellis and in a terracotta pot. Today I notice it has 3 yellowed leaves with spots and rings on. It reminds me of ring spots in orchids. Or some fungus? I really like the plant but will of course burn it if it's infectious. I haven't repotted or changed it's care.

What would you guys say? The yellow spot that can be seen on one leaf on the plant is from sunburn long time ago.

Thankful for any advice!

I am thinking perhaps bacterial blight. I have never seen that before. I would probably treat it to be safe with something like Physan 20 which is a bactericide/virucide/fungicide/algaecide. It is commonly used on orchids and the plants for various rots and diseases.

Thanks for the feedback Gina! I'm afraid Physan 20 isn't available where I live. I'll keep an eye on it, no new leaves yellow today at least.
