| Sep 1, 2020 at 18:27 | comment | added | emersonthis | @benn Is the brown discoloration on the stems consistent with powdery mildew? I've seen the dusty whiteness before, but not the speckles on the stems or the brown "char" after treatment. | |
| Sep 1, 2020 at 18:25 | comment | added | emersonthis | @benn I think baking soda works because it's alkaline, and makes the surface of the leaf inhospitable to the mildew, which needs acidity. At least that was my understanding. It's possible milk works similarly, but I'm not sure. I did a quick Google about the acidity of milk and it seems to depend on a variety of factors. | |

Thank you. | |
