it does happen sometimes - are you mixing it max strength?
when I had to use it a few years back I would mix it a little weak and turn one light off - spray that side and then wait until it was good and dry and then switch lights and spray the other side
do you have pm or are you uing it as a preventative?
I've noticed
Green Cure seems to prevent my plants from getting PM as well... I've got a couple questions for you.
Do you use it to kill PM that's already on the plant?
How late into flower do you use it, and do you avoid the buds?
General PM question: When spraying PM w/
greencure, do you guys wipe off the dead spores later, after it dries, or have you tried using a sponge soaked w/
greencure to wipe heavily infected leaves off?
