Powdery mildew week5 almost week 6 flower, so many searches so little good info

Hey guys im in my 5th about to be 6th week of flower and ive noticed ive got some powdery mildew. Its not terrible, id say about 10-15 spots total on 2 plants which are decently good sized.

The plants are grown in a tent with a fan blowing inside as well as an exhaust fan ect. never had any problems, in fact the PM was picked up from a friends grow tent who vegged these. It was sprayed prior to flower and there were no signs of it until a few days ago.

Currently keeping my temps above 75 during the day and around 65-70 at night (it gets cold in the bay area ca) humidity never gets over 60 (only recent its gotten above 55 at all only at night) and currently i have it below 50.

I got some organic spray SNS 244 it says its an all natural fungicide. Ive been using a q tip and spraying to any spot i see the mildew and it takes care of it for the most part once it dries.



MY QUESTION
how screwed am i? Everything ive read said this stuff is bad news once you get it. This will be my last rgow until next august so i plan to nuke the tent and all my equipment with a good bleach solution, but until then do i have a good chance of finishing flower with smokeable buds?

Any tips on how to take care of this stuff I know it cant be completely eradicated as it lives in the plant or something and the spores are everywhere in my tent, but as far as keeping it undercontrol should i just spray where i see it every day until harvest?

Currently this is my 2nd day of using the spray, ill spray in the morning and by the next day its all back. I moved my plants to help get better airflow going and trimmed a lot of the leaves that had it the worst (by worst i mean like 1 or 2 smaller than a dime sized spots on the leaf)

I notice it hasn't gotten onto the buds at all, although today i noticed 1-2 tiny tiny spots the were on some leaves that grew out of my buds close to the buds themselves. My biggest concern is losing my crop as like i said i was depending on this grow to get me to august since i have some security problems after this cycle finishes.


Basically am i going to have to just spot spray every day until i harvest for the next 3-4 weeks or what?

thanks for any feedback i get

Im gonna get some flac for this, but i have smoked buds that were mildewed before, i must say not my grow, i have never noticed any issues. I have heard things, but i don't buy the hype.
Any how what is the active ingredient in your spray? I prefer sulfur sprays, as they make a coating on the leaves the mildew can't penetrate. They claim you can use till day of harvest, but you will taste it too close to harvest. At this point what i would do is spray directly on all large leaves, covering buds with plastic or paper while you spray (should probably have fans off for this). I know this sounds next to impossible, but i would go get baggies and cover all the buds i could, then spray everything in the damn room, walls, floors everything. This will help to get rid of all spores around the room. If you do this once now you may be able to get rid of the majority of the mildew for the rest of the run and not have to spray at all again. Discarding leaves will be hard on the plants, but if they are too bad (starting to show damage more than just the mildew) you should pull them carefully before spraying and discard as far from the garden as possible. Wash your clothes well immediately after.

active ingredient is thyme oil, then theres a bunch of other added stuff like polyglycerl oleate, cod liver oil, lauric acid, and water.

Id prefer not to have to cover all the buds as thats a lot of work to do and i really dont wanna have to spray alllllll over my plants, it seems almost like over kill for how much there is in the tent so far.

Im also trying to avoid sulfur as ive heard bad things, especially this late in flower as far as taste goes. Im open to new things, i was thinking of getting greencure or w.e its called but im not sure yet i was gunna see how this spray goes (it was only 6$)

also its one of those thigns where if i can see the mildew on a bud after harvest, id just add it to my hash pile and make hash with it especially if i go with iso hash since im pretty sure alcohol will kill the mildew so it wont fuck with me.

i just dont want it to get crazy.

That far into flower you need/want an organic treatment that wont make the hairs turn red.

Get a 32 oz spray bottle...3% hydrogen peroxide (h202) use 1/2 a cup...... fill the spray bottle the rest of the way with water...... spot spray the PM daily as you see it up til harvest

Greencure is good stuff but it will make you hairs go red alittle.....you can add alittle greencure (2 scoops) to the h202 mix


You need to aero bomb or hand wash your tent after the crop is done bro.

If you pulled any clones from those pm infected plants.....more than likely the clones have pm too...hit your clones with EAGLE20

It can get out of hand fast would be my concern, not saying it will, but have seen it first hand. Don't forget that it is mildew and throws spores everywhere! therefore there is active spores flying around just looking for somewhere to land and start breeding again. Also the current infection needs to be suffocated to die, that is why i recommend the sulfur, works very well at this. In fact if you research sulfur on here you will find that sulfur burners are the tops choice of the best growers here. I like the spray for my room, but to each there own.
I do not believe the iso will kill the mildew though, certainly better than water, but i don;t think much. Good luck, don't think im being a dick, that is just the way i would go, and i have a room, not a tent, probably twice the size and i pack shit tight. But i love my garden and do not have an issue spending 3 hours in there putting bags on every bud.

I can never talk bad about anything colonuggs says, so go with that, sounds good to me.

Right on, ill try the 3% hydrogen peroxide mixed with water too if it gets any worse. Any idea where to get 3%?

Thats what you get at walmart or whatever, don't have to go anywhere special for this, just look for the old brown bottle.

ohh ok thats what i thought, im just so used to buying iso alcohol for bong cleaning ect that i wasnt familiar with hydrogen peroxide %'s and everything else. Im thinking this will be more effective than the current stuff i use, mostly because with a spray bottle i can accurately aim it and hit the right spots. This spray i have now sprays in a ring that always gets a fat circle around the PM but not the PM itself so i gotta spray one leaf like 2 times at weird angles so the spray gets everywhere haha


god i hope this problem is solved and it doesnt get out of hand. My plants finally turning purple too

ohhhh one more question, i have a HEPA air filter thing that im running into my intake fan (it helps bring down the humidity, at least keep it in check) but i was wondering if it would be beneficial to run it inside the tent for the sake of airmovement and the fact that its going to filter spores and hopefully cut down on the rate it spread. My only concern is if i run it will i then have to gut the thing and clean it to death to make sure my next grow doesnt get contaminated? Id hate to run my filter, have a few spores in the filter left over somehow then transfer into my newly sterilized tent because like i said i occasionally run the hepa into my intake to help lower humidity and lower temps

I am thinking you are talking about a fan/hepa filter in one thing. Yes i would move it into the tent and plant to clean or replace the filter for next grow, unless humidity is a concern if you move it then probably just leave it. What is you RH anyways?

This is right on good info, I will add a link with some solution strength for different things for overall plant health with it.

Good Luck it is a bitch of a problem at times

my humidity right now is 44% and decreasing, temps are stable around 78-79 we had the heater on to help haha. The problem is at night it gets freezing outside and my tent is in my bedroom so when i close the door with the window just cracked and the heater on my humidity rises to around 55-58 which is not good. Its annoying because if it wasnt so cold id just open my window and blast the hepa all night and it would keep my humidity down to around 45-50 but i cant do that without reducing the temps to a very favorable 65degrees.

Im going to check out this hydrogen peroxide solution tomorrow, ill get some h2o2 today when i go grocery shopping


Side note, what about harvest time? my plan is to only dry buds with no signs of mold together, any buds with mold or pm go straight into a special bag seperate from everything including where im drying. But should i do anything special when drying my buds that arent infected? Im afraid that when i go to dry them they are going to sit in the dark for 5 days or a week and get owned by PM in that few days. Especially the plant thats affected the worse because its basically growing 1 massive cola that i predict will take about a week or more to completely dry

thanks for all the advice guys you were really helpful and im glad i posted here instead of just GC like normal, that place has yet to even give me a response. RIU ftw !

You could get a dehumidifier in the tent too, if you drop the RH down around 20 - 30% or so its not ideal for flowering but it will definitely slow down the PM especially with the peroxide solution your using. Could be a good way to control it without shocking your girls too much this late in flower. just my 2cents....good luck man that shits a pain

Here is a saving tip for you and molding buds. The peroxide solution is great to treat freshly cut buds with a light case of mold. You simply spray your trimmed buds with this solution, drench the buds then place on screen or hang in a light, warm airy space until dry. Once they are dry from surface moisture hand and cure as normal, your mold will be dead, the h202 has totally evaporated.
I live where mold is a constant threat and this has saved me countless buds with no downside.
Happy Growing

Real Simple Solution (two parts):

In Veg - Eagle20 - This will actually prevent the mildew all together even if the spores are in your room. You can not use this once your in flower.

In Flower - OxiDate - This is the only thing can use in flower and on the flowers. Use a 100:1 ratio of water to Oxidate. You will find that is very very little. Don't get on skin or your in for the burn of your lifetime. You can use this up too the harvest day, it fully dries away in around 3 hours. Does not cure or prevent it, but it does oxidize any mildew or bud rot it comes in contact with and leaves the crystals alone.

Thats it, problem solved.
