What kind of fungus.....
I started my plants in my basement under a metal halide. After a few weeks I noticed whitish powdery blotches on older leaves. It rubs off to the touch. Leaves that were coated died.
Any idea what this is? I'm treating with a Bayer Rose anti-fungal spray. Would daconil be a better choice?
Sorry, no pics. I just treated again (the first seemed somewhat successful) and am hoping I won't see it again.
