Ctna 'Why Not' sick leaves

[james mickelso]

Bingo. Very nasty stuff. Looks like you have a good collection so disinfect everything. I would get a pump sprayer and spray everything down. If not, you can just cut off the infected leaf and dab powdered cinnamon on the cut with a Q-Tip. I get this all the time and that's what I do. But then again, I don't water overhead. I get no water on any of my leaves. I just water the media.
