2 thingsHey I grew Master kush which flowered in July 2020. they advise to max deleaf due to powdery mildew that can occur. Kush didn’t get it but OTHER strains did in flower close it it. I thought I had gotten rid of it. I was shutting down to move and I’m set up it’s coming back on 2 susceptible strains that I brought clones of to new space.
I know about keeping humidity in veg around 40, I use organic products on them for preventative and I’m really clean.
10X5. Veg tent. I’m using a standard box fan, and oscillating pedestal fan. Any advice ?? help a girl out
Thanks is that something I can spray them right inside the tent withSulphur works well if youre still in veg. Wettable powdered sulphur mixed with water and wash the plant down with it. Sulphur burner is the best option for gettiing it through flower if it doesnt go away.
Yep. Spray them down about 20 mins before the lights come on. Once every 3-4 days for a coulle weeks.Thanks is that something I can spray them right inside the tent with
That’s super helpful. An experienced grower told me about UV bulbs years ago and I forgot.2 things
#1. these is something about if the PM gets into the plant it will stay inside of the plant. Some of the bid time operations test for that before they dump money into the strain.
#2. Look into Solacure UVA and UVB bulbs, very bad for humans and do not go into the grow with them on but they will kill PM as well.
Hey monkeygirl, one other thing is that powdery mildew loves colder temps. Some strains are more susceptible, but lower temps are a big factor, even more so than higher humidity. Also an old hippy trick; spray plants with 1 part whole milk, 6 parts water. Every other day for a week or so.That’s super helpful. An experienced grower told me about UV bulbs years ago and I forgot.
you’re saying once a plant gets it, you can really never kill it off. It’ll be dormant within until conditions allow to come back. Ughh
the strain is PPP pure power plant. Also ICE is a problem. I was throwing out flower plants almost finished because PM took hold in late summer.

Hey RR1. Thanks very much I’m happy I reached out to join this community. always want to hear old school tricks that work Too.Hey monkeygirl, one other thing is that powdery mildew loves colder temps.

I need experienced growers like you people to be able to ask questions. gardeners that know much more than me that I can learn from. I appreciate all the respectful answers. I also saw right Away another female on here which is great. We chicks are out here and we make it happen !!Hey monkeygirl, one other thing is that powdery mildew loves colder temps.

If it gets into the plant it will continue to come back in later generations. I want to say it was on a podcast from shaping fire and steep hill labs. They went into how large operations will text a leaf sample from something they want to grow to make sure the plant is clean before they start using it in production. It kind of makes sense if you think about the money they have wrapped up on a large flower room at like week 7That’s super helpful.

Check out Liquid Copper Fungicide
Beach walker I really like that liquid copper, purple bottle. I’ve used that in veg and early flower. Really great. I wanted to get other gardeners take on this issue. Not just reading online and asking fellow at supply store I go to. There have been really good suggestions.Check out Liquid Copper Fungicide
I've used it on both white powdery mildew and septoria, and I've eliminated both of these issues with as little as three applications, although with septoria I also burned sulfurBeach walker I really like that liquid copper, purple bottle.

I really didn’t know that once it gets into the plant itself it stays in it. I thought that once your room/space had it- you had it like a disease and could get it to go dormant but conditions could bring it creeping back again. I was taught that by someone. Oops
I am not over run with this but it’s definitely in a couple of the mid sz clones I brought from my old space.
I used this organic product yesterday, I’ll upload a pic later Today.
I also had pm about 3 yrs ago used Banish over and over I feel like for couple months. it was the best one I came across at that time. I’ve been great until I put that one master kush thru flower and it affected others this past July. And brought it with me to this new space.I've used it on both white powdery mildew and septoria, and I've eliminated both of these issues with as little as three applications, although with septoria I also burned sulfur
The septoria has been gone for four years and the wpm for about a year, although it did pop up in a cloning tray a few months ago but I had that in a separate area, hope it works out for you!

I sprayed yesterday and today. Everything is looking pretty good. There are some other guys that responded to me said to use the powder sulphur.

good infoSulfur works great in veg and early flower. You need something to kill spores and the tube that feeds, that’s the part that goes into the plant and will make the pm reoccur even when you don’t see it anymore. Geraniol does this I’m pretty sure and something like the product banish is pretty cheap and easy to get. What also helps is silica and beneficial microbes. The Dutch completely killed pm in their strawberry fields using silica and milk foliar sprays. I used power si, OG Biowar and em1 microbes as a foliar spray once a week and I would hit them with purecrop1 and geranium in between those sprayings and I haven’t seen pm at all in my last 2 full runs and it’s not on the mother’s either. You can kill it permanently but it’s harder than just spraying once or twice and poof usually
