Hi all, I was hoping for more advice on my Vietnamese mint plant. About a week ago, I noticed white fuzzy spots on some of its stalks so I pruned off many stalks/leaves with the white fuzzy substance (thinking it was a fungal infection) and sprayed it with eco-fungicide (active ingredient potassium bicarbonate). It was fine for a while but today again I've noticed white fuzzy spots on the stalks (pictures attached). Just wanted to see what others' thoughts are regarding whether this is more fungus or whether it is bugs. Should I respray it again with the fungicide or use something different? We're in Australia and this summer has been quite humid. I have taken the plant out of the pot it is in so that hopefully it gets a bit more airflow. Help! Thank you in advance.
