Without a doubt, that's PM. Mycotoxins will only be concentrated if you make a -->concentrate<-- 100% removal of PM is something that is very difficult. You can remove the majority of it by dipping/swirling the harvested buds in a strong peroxide/water solution, then drying/curing as usual. We did this at a recreational grow in Oregon but it didn't get all of the PM off, it didn't even get it below the cutoff for fungal testing. It makes it safer, but not safe.
I would not keep that plant, just my opinion. Also once MP gets into the plant it can use the plant as a host and it will just keep coming back even with low humidity and correct temperature.money shot
money shot of the FP , this came to me as clone, and think it might got jammed up when some other plants went south and one developed root rot? right now my room is 76 degrees and 40RH if i try and go below 40 RH my temps skyrocket ?
Harvest everything, bleach the room, wait 7-10 days, bleach again before the next round. Go OCD and clean every groove and crack in your room. PM needs a plant host to survive, if it doesn't have one for long enough it should die off. Day/night temperature swings of more than 10 degrees, high humidity, low airflow, dirty filters, and a dirty room in general are usually the main culprits of PM. I had a boss who brought his dog into the flower room and sure as shit 7 days later we had mites and PM on the same path where that little bastard wandered through.
PM is spread by spores. The spores can live in adverse conditions for months. The spores are in the environment and will grow when conditions are optimum. Clean as described above but look into a product that will kill the spores. It keeps coming back because;
#1. The environment is ideal for growth
#2. The spores have not been killed.
Did a little searching on Google and found this.Bleach will definitely kill the spores. However, I thought PM was an obligate parasite and the spores died if they didn't encounter good growing conditions after a few days, but I'll have to dig more on that. In my mycology courses I learned that PM is everywhere and in every breath you are breathing thousands of spores, maybe the variety that harms cannabis is tougher/differentEither way a clean room with proper temps and RH are definitely the best prevention. Being so far into flower really limits the options for saving the crop.
Ok how lol??Pm is easily treatable naturally.
It is systemic and can be eradicated with due diligence.
I had pm in my flower room and have completely removed it. While in flower.View attachment 944828
Sorry friend, but yes, you have white powdery mildew...and you are 8th week in flower. Personally, I don't keep this when this late in flower...I throw it out. But, to each his own....hard to admit sometimes, but true
Bummer man. I know some people do a h202 wash before drying, never done it though. Best way to prevent it is routine sulfur burns. In my veg room i do it once a month and in my flower room before i rotate them in i do a sullfur burn . Its cheap and effective. I havent seen pm in 8 years doing it that way. Looks great aside from that8th week of flowering and would appreciate some more experienced eyeballs give me their thoughts on chances of this being WPM or not. i have good vent i thing? 6" out, 4" in 45-50 RH temps high 70's-mid 60's at night? i read a some other older threads but they older gave me the noids as i'm baked... send well wishes and kind thought but i can handle the hard truth if need be don't sugar coat it.
thanks in advance guys
