I think I may have PM "powdery mildow" my room is 2x7, I have A 175 cfm fan running 24-7 and one 16 in fan on the same. Ive seen some yellow leafs and what might be the start of PM. What do I do?
Hows the humidity? If its PM spray with a mix of 9 parts water 1 part non-fat milk. Add a tiny bit of potassium bicarbonate if you can get it and a tiny amount of soap.
I was wondering the same thing...to get PM wouldn't you have to have a problem with temp and humidity?
I keep a small note pad next to my cabinet and take daily readings of temp and humidty throughout the on and off periods so that if in the future I have problems I will have some info to bounce ideas of from.
Remeber that humidty rises during the 'dark' cycle and some people end up running a dehumidifer during this time...
I misted them on monday but they already had seen some signs of the PM. BUT I was hoping I was wrong. wount do i t next time. I already used a spray from the grow shop
