powdery mildew. lots of easy remedies. I use Safer brand organic anti fungus spray. Neem oil sprays, baking soda sprays, hydrogen peroxide sprays. Add one or two drops of plain dish detergent with the home made sprays to help 'wet' the water.
Where are you at in the cycle? That's a pretty nasty pm problem. Are you indoors or out?
Shovels remedies saved my ass
Never had it on my grow, just roses & lilacs. But yeah, definitely soap for wetting agent. THAT SHIT'S WATERPROFF! Just wanted to add, soap, not detergent. Best would be Joy (non-ultra, not concentrated original). Detergent burns plants.
Good luck!
I am outdoor grow and that is the worst of the leaves. I wanted to take the worst leaf to show you. I am about a month till the ends I think. They are Northern Lights. Don't see any on the bus or the tops of the plants just the lower half. Was told to wipe or pull the leaves. They were in a gazebo with 4 walls to hide form the dew in the night air as well as if anyone came into my yard they have no right to look in there if they are from the city. Kinda a long story but my neighbor has turned into an asshole over property lines so I thought if he called someone over I needed to have them hidden. I have one girl that I might give a few days and if I see anything she will have to come down. She is an auto flowering and might only have a week left so if I at least get her down I won't feel to bad. Just would suck to lose all 4 NL.
I've always used plain dish detergent. Dawn, Joy, we buy Ajax brand. NO added bleach or anti bacterial stuff. That's the only kind we buy so I can use it for plants and the dishes. I've had plenty of experience with PM as my wife has a phlox plant that has been highly susceptible to it. This year was an exception. No PM and actually they are in a second bloom right now! Most Excellent! It's also been a very good year for bug pests (meaning, very few bug problems) Even house flies have been few.
Maybe I'm not reading it correctly but do you have a week or a month left? Thought you said a month in the beginning and a week at the end. The problem with PM is when you see a little bit of it, it's already everywhere and that leaf is covered. I'm sure your going to have it on all your plants soon so I would spray with greencure or some other potassium bicarbonate product, I doubt you will get rid of it completely but that will at least help control it. If you put tarps around a gazebo did you put any fans in there? Fo future grows, air movement is a great way to help prevent it and spraying with a treatment or using a sulfur burner before you get it and at the beginning of flower is the best thing.
I have maybe a week for my on autoflowering but at least a month for the 4 NL. I will go see if I can find that greencure. I just bought a fan just for this but I guess it didn't get in there in time. I think it is cause I watered at night and it got condensation on the roof. Live and learn and learn as you go. I no longer grow pumpkins or zucchinis because they always seem to get this on them. If i try the dish stuff can I still use the greencure if I can find it?
Ouch! Best time to water is am, before 10am. After that you can get sun scald. Never water pm as water will stay on plants & attract all kinds of fungus spores, what ever happens to be in the air. It's humid in my area, so I have to make sure I do nothing to block airflow around my grow. Keep it clean, no dead leaves hanging around & other organic debris, & good airflow. Thats the key to prevention disease & insects. Next grow, start using the fan from the beginning. Oscillating fan.
I usually put a squirt of dish soap into anything I spray on my plants, foliar feeding, insecticide, fungicide. Most things need it as a wetting agent.
Next year I will do better. This is only my 3rd year outdoors. Last year they were small PK kush and one purple kush but I had 13 plants. I didn't want that many this year so I went for larger ones and kept it under 6. I really want to do a purple as well as something like blueberry next year. I have always had them purchased for me but that connection is now over. I will be on my own. I think I will try lolly popping as well next year. I would like ones that are less time from start to finish as this part of the year is way to much of a worry to have them out in the cold and have to use the gazebo. If I do use the gazebo I will make sure there is a fan or 2 and never water at night and make sure there is good air and no moister. I learn more every year and this year it was PM. I hope they turn out though. I guess no more food for the autoflower and just flushing now since it is a week or two till done.

Let me know if this stuff will do. And if I can just use it as is or water it down.
I fear chemicals. Do you want to smoke them? Some where I read a post by shovelhandle. A bunch of natural remedies for various fungi. Let me try & find it & I will tell you where it is
Ok well I went with baking soda with a few drops of dish soap to keep it on the leaves. I did take off the worst leaves. At this point I have one girl that is almost done with no white on her so if she is the only one who makes it I will still be happy. I mean I only smoke it when my arthritis gets really bad so one plant will probably do me a year. I sprayed the crap out of them. I did find a small white spider which so far from what I have read he is a good one. I am letting it dry and then I will turn the fan on. I have also taken parts of my walls off for ventilation so it doesn't get wet in there again. Live and learn as well with the help of all you good people. If I have to do this every few days for the next month till they are ready I think I had better go buy a better sptay bottle then a hand held pump one.
Oh heck! It's post #2 on this thread & here am looking all over the forum for it. But yeah, what he said! LMAO!
Well I was just out there and they are looking good so far. Little on the wet side. I did put a tall isolating fan out there and opened a bit of the top of the gazebo wall for air flow. I am crossing my fingers this works. I did take off the worst leaves. I think by next year I will know so much more. Such a learning experience. Ok so what is the best nutes to get right now? I think it is time for some as it has been a week off the 20-20-20. Someone said bud blooms. I can only go to a hardware store as any pot store is far. So what to get and how much to give them and how often? Thank again so much for all your help.
Well I just went and checked on my girls and they look great, I was worried about being told to remove so many leaves but they still have tons on them. I am going to go get some 10-30-10 today to give to them. The fan is going on full which only bows a little on them. I do worry that now that we are in a cold rain spell they won't be getting the light like they used to. I do notice that they look like they flowered more. Is it my mind hoping or could this be true?
The best remedy for and fungus,mildew or mold is ventilation,ventilation and more ventilation... Humidity should be at a low but not low enough to take away from the plant's... They need a lil' humidity.... Even with a hydro system... Where water and moister are present all the time then ventilation is key to no condensation that can raise humidity and there come's the mold,fungus and mildew... Just a preventive note..
So the mildew is under control. You cant even see it but I ended up getting some bud rot. Next time I go all organic so no flushing as I am sure that is what did it. My NL have small buds but the tricomes are almost all milky white and the other things are turning brown. I have organic for the last leg of the grow. I am hoping it will be soon as I need to get them down and the nights are getting colder. Next year I want a faster stain and I think that I will lolly pop. I have learned so much from this second grow. I hope you all can and will be here for me next year.
