ASK ED MARIJUANA GROW TIP #43: DEALING WITH POWDERY MILDEW
POWDERY MILDEW: As you can see from the first photograph below, my plants were suffering from powdery mildew. I sprayed the plants with a solution of Ed Rosenthal’s Zero Tolerance Fungicide diluted slightly with 1 quart of water to a gallon of the fungicide, and added an ounce of Serenade® concentrate to the mix. I used a hand compression sprayer with a long flexible wand, so that the spray could reach all areas infested. The powdery mildew was on the top of the leaves, so I did not need to spray underneath. The result 24 hours later—no sign of powdery mildew remains on the plant. I blended Ed Rosenthal’s Zero Tolerance Fungicide and Serenade because they work synergistically to combat powdery mildew and prevent its recurrence.





Ed Rosenthal is a genius.
In addition, keep the humidity in your grow room as low as possible. 35%-45% should be your goal. Also, keep the air moving. Oscillating fans are cheap and work wonders, you can’t have to many of them.
Hi Ed –
I stumbled upon your website through Google after doing some searching for “why marijuana gives me anxiety/paranoia” etc…
This could be a very long comment if I’m not careful so I’ll try and sum it up as quick as I can
I am 28 years old. I began smoking back in Junior year of high school. We had an okay time on it, I guess. We laughed a little…and got the typical zombie like effect from it. Couch lock, lazy etc… It wasn’t till shortly after high school that the high started effecting me differently. I started getting bad trips. Anxiety and an uneasiness would creep in with the high. Leading to almost panic attacks about life changing etc. Long story short it led me to quitting cannabis altogether because I wan’t having a good time on it.
I thought it was just me but LOTS of my friends quit it too for the same reasons.
My father and I have a really close relationship with each other. He is my best friend. He’s currently 65 years old. Him and I have always talked about everything together. From women to drugs. He was a hippie through the 70′s and smoked a lot of cannabis. He still to this day smokes a little on the weekends but usually has to combine it with a bit of alcohol to keep the anxiety and chest pains from starting. Please read on…
Ever since I first started smoking back in high school he would always rave about how much “better” the weed was back in his day. By “better” he means “fun.” To this day he talks about the “lids” they had in the 70′s and early 80′s were full of seeds, and the plants were a dried brown color. He states the high was “amazingly fun.” An “instant good time” as he put it. Never any paranoia, anxiety etc. It induced extreme laughter to the points of tears coming down your face. Gave people an uplifting mental high which always made anything they did, interesting and exciting. He always says the weed back then always put you forward never backwards. He actually has an audio recording of him and a girl he was dating at the time in 1977. They sat in his car and smoked a joint on a sunny summer day. About 6 minutes after the joint was finished, he accidentally hit the windshield wiper button and they started wiping back and forth fast. The next 35 minutes of the recording was just both of them laughing hysterically over the windshield wipers.
He states the world could be coming to an end, you just lost your job, girlfriend dumped you…..and you would STILL have a good time on this weed.
The point I’m trying to make here is he says it was always a fun high no matter what the circumstance or situation.
He started noticing the “fun” high start diminishing around 1985. The weed occasionally would make him lazy, unmotivated and anxious. He dismissed it as maybe it was a problem with the “set and setting.” However, it eventually got to the point where “it was all bad” and he started having to drink a few cocktails to help level out the anxiety the cannabis produced. The weed was never the same again, he puts it.
A lot of his close friends noticed the fun high started to become fewer and far between until eventually it disappeared and nobody saw it again.
Now I’ve posted this on some forums here on the internet asking about all this. Asking for people’s input. Especially people that lived,and used cannabis during the 70′s. The only comments I receive are from young adults in their 20′s and 30′s making uneducated and stupid comments about how “everything is more fun when your young. The weed is way better and stronger. It has higher THC which makes it better, duh”
This is how they explain why the high was more fun for him. Because he was young…now he’s older and it isn’t.
This is really not valid though. For one, I don’t like the quality of the high from today’s weed. My friends don’t. My fathers friends don’t. And by looking at the 1000′s of people at Hempfest here in Seattle every year, it looks like the majority of people using cannabis don’t. But of course, the majority of people don’t have anything to compare it too. To me it looks like a bunch of zombie’s walking around. No one is laughing…no one is really socializing and nobody really looks excited like their enjoying themselves.
I obtained a marijuana permit a few years ago in hopes I could find some “fun” stuff at any of the hundreds of dispensaries here in Seattle. I haven’t had any luck. They sure do have a lot of strains. The names of the strains sound appealing…the smell is appealing and the general overall appearance of the buds look appealing. But the high is the same old negative shit. It seems everyone is caught up with the look, smell, taste and “stickyness” of the buds. Hardly anyone really talks about the quality of the high. Which to my dad and I is the #1 reason for doing it in the first place.
I’ve read breeders began aiming for high THC content in their plants since the 80′s. Maybe this explains it? I’ve read CBD is important in plants and the majority of today’s cannabis has hardly any of it. I found the strain “Harlequin” at a local dispensary which is suppose to have high CBD to counteract the negative effects of THC (anxiety etc) but I didn’t notice a big difference on that stuff either. I still get anxiety and a general nervousness on it.
So to sum it all up. My father is a firm believer that a happy plant produces a happy high. The stuff they had in the 70′s was brought in from Mexico and Thailand. It was grown under the sun naturally, the way nature intended.
He says the plants today are pretty much living a nightmare and are being tortured. The breeders leave the lights on way more than what is natural. The breeders never let the plants go to seed. They just keep cutting the buds off and letting the plant regrow, again and again. So in the end your smoking buds from a sexually frustrated female who is maybe two or three old. Marijuana plants aren’t suppose to stay alive that long in the first place.
This is the only reason he could possibly think the high is no good anymore.
I’m hoping for any positive feedback/input regarding all this. What are your thoughts? Do you agree/disagree? Do you notice the “fun” high not quite as “fun” as stuff when you were younger?
Thanks for reading this long comment/story. Greatly appreciated!
Jeff, I am a chronic smoker for the last 25 years plus. Indica varieties tend to cause these same effects in me. They are high in THC, thus stronger, but lack the fun like you describe. Try a strictly Sativa strain for the effect you are looking for. I doubt you will find anyone growing it because Indica varieties are stronger and produce denser buds. People don’t have to smoke as much to get high, and that’s what sells. Peruse seed sites to find a nice Sativa, they usually describe the high. My personal fave is Love Potion. It will give you that happy, fun, cerebral high without making you nonfunctional. Its not a money maker though. Good luck and get happy.
