My girls are currently in the seedling stage, had a high humidity until recently but lowered to 50's right now...
A few days ago I noticed something strange on my fans... then upon checking where the fan blows, I saw that a white dust seemed to be forming on my rdwc (currently not in use) and on my clear propagator cover which happened to be just left under where the fan blows after I removed it from the propagator. The girls seemed fine with no sign of this dust atm.
I took the girls out, dismantled the fan, cleaned all the tent and everything around with 3% hydrogen peroxide. Washed the propagator with bleach and rinsed it thoroughly. Then mixed the peroxide with 9 parts water and sprayed the girls with it...
And when the lights were out, I took the girls out to another room and upped the temperature to above 90f for a few hours, as high temperature is said to kill powdery mildew for sure.
It all seemed fine for a few days but today I noticed the white dust slowly forming again in the propagator walls, it almost feels like residue dust which you can wipe with your finger (and you actually can), but I didn't use anything that can leave a residue as far as I know.
Here are some pictures from when I noticed this happening the first time. Any ideas to what this might be and any suggestions? The girls are still fine and this dust is not forming on the leaves right now but they are so little and I am not sure what might happen next...
I thought this was powdery mildew but is it normal that I only see it on the equipment?
