I don’t get it. I have had this issue my entire grow and cannot fix it. It’s spread into my flower tent and so ready to my bubble cloner.
Some leaves have it on them. And when you shake the plant you can see it go airborne. How the hell do I cure this? My temps aren’t too high nor is my humidity. Flower tent has LED and my veg tent has 400 watt MH. I have fans blowing in the tents and exhaust fans. I’m quite puzzled. I don’t wanna ruin my crop as it’s my first round with the hammer shark and would like to be able to smoke it. This is also my third grow and never had this issue.
 
For the most part yeah. My temps don’t dip below 22c at night. I am growing in a basement. And it’s winter now. But I never had this issue on my previous grows in winter.
 
all the time your temps should be for leds atleast and to keep your dehumidifier running well should be 80f or up I like 82F-86
 
that's pretty low your dehumidifier aint working what so ever at that point get your temps up 27 at all times simplest thing u can do
 
Lowest my temps drop down to is 21C. And the highest the humidity spikes to is 43%.
I guess I need to get a heater for my back room now eh? I know PM happens from dark cool and damp places. So it’s clearly occurring at lights out. Now how the fuck do I keep it from spreading or eliminating the problem? I don’t wanna lose my harvest and have to turn it all into cream. This is a new strain I grew and wanted to smoke some come January.
 
One little thing I do in the winter is run my lights at night and the dark period during the warmest part of the day.
 
once I see pm I cull many things you can do I just don't risk if its a bacteria it should work but if its like eagle20 no bueno
 
Never had the issue last winter. But now that I think about it I never had the home made bubble cloner. So all that water sitting in a tub for my clones is clearly adding humidity into my grow room where my tents are. That has to be the culprit. It’s the only thing that’s different than the first grow If I think about. But I know my tents are gonna need a deep clean. Top to bottom.

between grows I bleach the fuck out of my whole room and I ozone it not recommended but u should prob leave room and seal it up I do it for 24hrs and it goes off then I give it a few hours to dissipate with fans shooting outside
 
You can try green cure( potassium bicarbonate)but if your entire crop is infected,your kinda fucked and should just cull it and start fresh..
 
Yeah my room isn’t just a grow room. There is other things back there like the furnace haha.
And I always have a veg tent running so I can keep clones and mothers alive. I took some pics they don’t look to bad. It’s the bottom buds that I’ll have to turn into cream. Top ones may be smokeable.

Even with low rh pm can still grow. It has gotten in your room somehow and now the infection is spreading. Just because you added a cloner doesn’t mean that’s caused pm, the spores have to come from somewhere. If you don’t have access to green cure even high ph water 8.5-10 will kill the active fungus but is not a cure.
