High humidity, no air circulation, 12 hours = powdery mildew on your plants.



DUH!

I am feverishly looking for any signs of more of it, none so far. The spores had just started on 2-3 leaves. Leaves=Removed, Heater=On, Window=Open, Humidifier=definitely off, fans=On. That fan will stay on 24/7 now.

Let's hope I nipped it in the bud.
Oops.....how about an anti-fungal spray like Serenade?
