Mold/Mildew

[Iheartoregon]

Hi there,

I have a plant that I’ve noticed some small grey mildew on some of the leaves. I keep picking the leaves that it shows up on, but after floating around and reading stuff, I’m now paranoid. I’ve attached pictures of my plants and how far along they are.

I’m wondering a couple of things. I’m wondering if I need to do some sort of a spray on the plant? If so, can anyone tell me how I deal with this? Or what the process is? I’m sure it’s been written about before. I apologize for being so lazy. I’ll probably go try to scour the internet and see what I’m able to dig up. But I figured I’d rather ask someone on here and have active dialogue rather than just reading something that could be more general and maybe outdated?

Any info you can give is greaaaaaatly appreciated. Thanks and I hope everyone is doing well!

I don't see any mildew. If you can edit your pic and point out where you see it.

Here’s an older pic but this is what it looks like.

I had the same issue. Tried diluted apple cider vinager. Dish soap and baking soda. My advice it control it quick. Look for the source and clean or cut infected leaves. Once it's on the buds I wouldnt smoke it. Just my opinion.

 

[go go kid]

you need the baking soda one or a 40%milk and 60% water spray will also work

 

[Kid212]

Combine one tablespoon baking soda and one-half teaspoon of liquid, non-detergent soap with one gallon of water, and spray the mixture liberally on the plants. Mouthwash. The mouthwash you may use on a daily basis for killing the germs in your mouth can also be effective at killing powdery mildew spores.

thanx i was just looking up the quantaties of baking soda as i use the milk solution

Alright! Just gave it a nice spray down using a 40/60 milk/water ratio. Already dried out. I was worried about that leading to more mildew/mold but it looks alright now! Nice and dry! Now let’s see if this helps prevent further mildew. I’m also gonna stop with nutes. Alllllll natural from here until harvest!

how is it lookin?

 

[Iheartoregon]

I gave it a nice spray since it’s like 80 out and dried up so fast on the first application. The first one was pretty light so I gave it a bit more. I’m wondering....when it pools and dries, won’t it look like mold? Or doesn’t go away? Also I was wondering about the smell. Right now it smells a bit like milk on my plant. I assume that’ll go away too with time? I’ll check on it again tomorrow, but am just impatient so I figured I’d ask haha. Thank you for pointing me down this road in the first place, I appreciate the help!

Jeez....crazy the advice you get on here sometimes. Absolutely do not suggest spraying your buds with anything at this point in your flowering stage. What you have is called WPM. White power mildew. It develops when plants don’t receive enough through light or airflow. It spreads like wildfire if left alone and even still spreads while treated. The best and only advice I will give you is to defoliate your plants very well. They look healthy, open up areas around your bud sites, removes any small branches that are clogging up areas. And then continue to monitor daily if possible, each time taking a pair of scissors and cutting out any more WPM developing. Be sure to walk around your entire plant and pull back bigger bud sites. Good luck I’m dealing with the same thing but it’s manageable. Next year try to get them more sunlight earlier in the day because of the fall dew that sets in and/or more air flow in an open area.
Happy growing!

 

[Kid212]

Thats a very good suggestion. I do get a lot of morning dew and where the plants are get blocked by the houses for airflow. Will be keeping that in mind for next year.

Potassium Bicarbonate is what I used. Diluted in water, cleaned with the sun cycles, took a couple treatments and it took it away. Look up potassium bicarbonate in here and you will find a good tutorial on it.

GL!

Throw a couple fans out by your plants next year. Start around September at night, until they finish. You will be very happy with the results. It really made a huge difference for me.

just curious as why you would spray your buds with a chemical? What you suggested is inorganic. You cant assume water will dilute it completely, at this stage in his flowering you wouldn’t want to spray your buds with anything. Very key to keep things as dry as possible as moisture and no air flow actually cause WPM. The best thing if you wanted to use any moisture would be to wipe down each affected leaf with insecticidal soap but that’s not really necessary if you defoliate the plant properly. Healthy plants can take a lot of stress.

 

[Iheartoregon]

Haha well shit, this sucks. I’ve been asking for a while and then finally got a suggestion and ran with it oh well I guess. Like I said, it was drying up really nice because it was pretty hot. I walk around it almost every day and look very closely for any new growth of the mildew.

I read a lot of different things aboutdefoliation and this makes sense. I’ve been doing it somewhat regularly, just on a conservative basis because I wasn’t sure who was telling me the right thing haha.

tomorrow is a new day, and I’m gonna hit it hard! Try to get it in the sunlight as early as possible and do some major pruning to the leaves to get some good air flow.

lets hope all of this works and i didn’t stumble at the finish line! I’ve still made it further than I did last year, so I guess that’s something to be happy about. But I wanna get something out of all this hard work and diligence! Haha

I seriously appreciate everyone chiming in and helping out. I’ll post more tomorrow after I clear things up a bit.

 

[ryeguy]

You’ll definitely get a harvest sir. Just have to be more diligent than other grows in your future. Clear away any big mature fan leaves first, small branches etc. 20% volume is good to start see how they react. All the best!

 

[Iheartoregon]

Much appreciated man. I’ve been doing around 20% every couple of days. Maybe I’ll get a bit more than that out tomorrow. We’ll see. How long should I wait in between these increments? A couple of days to see how it affects the plant probably?

 

[ryeguy]

I usually go a week depending on the severity of the WPM coming back. I find defoliation really helps, from there I just monitor each plant and pick a few leaves at a time if needed. It’ll all come together! Good luck.

Sure thats not pollen? Any herms?

Just doing this one plant. And nah it’s not herming out at all. I’m kinda hoping I do find some seeds though, because this type of plant (so far) is exactly what I’ve been looking for.
