Ok, let me see if I can provide more details. First plant is onc sharry baby, second is a gongora, third is bulbo picturatum. Water is rainwater and I am a constant underfertilizer. Yes it is a King Canopy GH. I'll try the Thiomyl and see what happens. And there is a lot of air movement in the GH, leaves constantly stirring in the fan created breeze.
Do we all agree that chopping off the affected areas of the leaves is the best course of action? And then treating with Thiomyl and cinnamon?
