Looking really nice and good luck with those shrooms! I think mushrooms are easier than pot . Been taking a few this year they have really interesting after effects, definitely one of the most enjoyable hangovers I have ever had. Really enjoying reading the mass of knowledge gathered here.

Hey @Sebring, I was looking for a cheap cure for a late PM issue. I still have 3 weeks to go and I’ll never make it if I don’t do something. Money is always and issue for me lately so I’m trying to use something I have on hand.
I came across a post in this thread while searching. You mentioned Potassium Silicate and Calcium Chloride. Would the CC be effective on its own? I don’t haven any silica atm but I do have a small bottle of CC.
If you happen to know any other ghetto remedies I’d love to hear them. I hope I have something here I can use. peace

Hey, I found a bottle of Serenade and am in the process of using it. I got one third of them washed in it. 10 more tomorrow. I started late so it should be no issue getting finished tomorrow. If you have any thoughts on the Calcium Chloride… I’ll google it up if I think I need something else. I
'm hoping to make it to harvest and then doing the bud wash buckets when trimmed, to be safe. Man, that Sebring’s Revenge is a tasty one. So is the Maui Sunshine. peace

CC or Magnesium Chloride should slow the PM growth, by changing the pH levels on the leaf surface. These use both in grape production for the same thing. Grape production recommendations for spray dosage are going to be your best bet.

Thanks for the tip! There seems to be a lot more info on the PM subject in regards to grapes than cannabis. The first link I went to is very in depth. It’s from the BC government. Lots of stuff to read. So far it seems the key is to start treating the plants from birth.
Do you have an ideal dose for the CC? like per gallon of water or anything I can scale off of?
I’m going to do the other plants today and if I have time I’ll bleach the floor joists above them. I’m going to hang some Tyvek or Panda Film for the ceiling next time. I’ll be saving for a ventilation system next. I need a good filter for the intake. I don’t care about scrubbing any smell.
That PM seems to be everywhere around here and it’s a very dry climate. I remember being told a time or two that PM wasn’t here before the cannabis gold rush. I never saw it ever before I moved here.

If you can get the humidity way down then that will stifle the PM as well.
I know there is a research\trade paper on the CC that gives a dose, but I can’t remember what it is.

Yeah, I need a ventilation system. Hope to have that by summer. Thanks

I believe a couple days of really high heat kills it too. Don’t remember what temperature was optimal though. I remember doing it a couple years ago and it worked great, aside from the plants needing a week to recover.

I saw that. I was a little surprised. I can get some PC if I can make it a week or so. I’m hoping this Serenade will get me that far.

Soma mentioned alkaline water for pm controll, easier to make it but they do sell 9.5 alkaline water by the gallon at walmart

@Heritagefarms a solution to be applied as a foiliar at a pH of 9.5? Really?
No issues are known to occur with hydrogen peroxide, which dissipates rapidly after application. JMS Stylet Oil is actually a very good late-season spray to reduce powdery mildew and European red mite. There is some evidence that late applications depress Brix (sugar) accumulation due to a temporary reduction in photosynthesis. Research conducted in California indicated that Stylet Oil had no effect on fermentation nor are there any obvious issues with the phosphorous acid products.
and
I see a mention of making use of vinegar which will lower the pH. I have seen powdery mildew growing on an alkaline substrate like concrete.

Thanks for the links. I like that first one. I feel like I may be able to handle it with all of that. Getting ready to look at the other page. Thank God my plants don’t look like that pic on that first link, heh.
I’m just now getting spots. I should have acted sooner. I was trying to pull the leaves as I saw it because at first it seemed like only one plant was having a problem. But it’s moving to others now. Still just outbreaks of little spots but they’re serious.
I have milk, baking soda, hydrogen peroxide, and apple vinegar. Also Serenade bacterial spray. That’s what I started with. I’m thinking of taking the plants out today and bleach it down. All I have to do right now is make it 3 weeks without losing the plants. peace

Some interesting books about this. Paul Stamets and some other guys. Mushrooms are so cool.
And since you are a fan of No-TIll and no chemicals, mycorrhizal mushrooms might be just your next big grow booster buddies

I’m actually looking into putting oyster mushrooms into my no till beds. I think it’s worth a try.

I dont expect it would work good may be slightly better then plain water, that shit grows into the plant and is a pain in the ass to get rid of.

Unfortunately I have had the experience of the taste even in dispensary weed. I abhor this particular pest but it means throwing out your plants that have it and cleaning the entire room to eliminate it.

Oysters grow out of logs pretty easily can be done using wooden plugs or dowels inoculated with mycelium driled and pounded into the logs.

The Serenade seems to have worked for the time being on the PM. We’ll see what the future holds. The only chance it seems is to catch it early. That shit creeps me out, heh.
I did major leaf removal on all the worst ones and then sprayed them very good. The last 5 I treated in the grow room. I’ll be dipping them in buckets at harvest to be sure. I want this harvest. It’s my first seedless run in a while, lol.

I dont beleive you have to throw out plants just because they have it , if caught early I actually find it rather easy to get rid of. People say it is systemic but that has not been proven, it grows into the plants tissue and there for can lie dormant but has not been shown to be truly systemic
