Please help identify this

Anyone able to identify this? I have no idea what it is but i have sprayed mildew killer on these that should be ready by Christmas but now I’m concerned. Thanx

White powder mold, you’ll need to treat with diluted peroxide. Either before harvest or after.

Just for consideration - it may also be minerals. Are you using an ultrasonic humidifier with tap water?

I found out thru my local htg store it was indeed white powder mold! I have fixed the problem with PureCrop1
