potassium silicate liquid blend
I've got Armor Si which is potassium silicate (no curdling needed). I'll give it a test! Thanks Smeegol.
Interesting study on potassium silicate and PM done here (if you believe in science I mean):

Abstract:
The area under the disease progress curve was reduced by 65% and 73% in the foliar and root treatments, respectively, compared to control plants, as a consequence of reductions in infection efficiency, colony expansion rate, colony area, conidial production and disease progress rate. However, root application of PS was more effective than foliar application in reducing most of the epidemic components, except for infection efficiency. This can be explained by the high Si concentration in leaf tissues with root application, in contrast to the foliar treatment where Si was only deposited on the external leaf surfaces. The effects of PS reported in this study demonstrated that powdery mildew of melon can be controlled, and that the best results can be achieved when PS is supplied to the roots.
Interesting, because I don't use PS along with my MC, but
@farside05 does!

Friday shelter-in-place update! Cloudy at the moment but it was sunny earlier, so the plants are all outside for now. Staying with the powdery mildew discussion for a minute, I pulled the clone mothers out of the garage today (for the first time in a few days) and they were all getting PM, so I thought I would run a test of three products: neem oil, castille soap, and SAGFF.
At this point I can tell you that the castille soap dried first, the neem second, and the SAGFF took a long time. I can also tell you that the first two eliminated most visual signs of PM, where the SAGFF leaves look the same as before spraying. I will see how they look in the morning.
If the SAGFF plant is still covered I will spray it with potassium silicate and see how that does. For
science!
About the same, thanks for asking (day 15):
The two AF-47's (day 17) are close to level with each other in height now. Here are the spring three:
That's all I've got today. I'll get some pics of the GT and FP tomorrow so you can see how they look on flip day 19.
and stay healthy.
