God, if powdery mildew was a man, i would honestly kick the shit out of him and would happily go to jail.

I FUCKING HATE THIS SHIT. Now i spent about 60 e. to Buy a Fungicide called Actinovate, why actinovate? cause i wanted to keep using it until very late of flowering TO MAKE SURE SHIT DOSENT GO WRONG! but what do you know PM IS BACK AGAIN.

Now I have 5 plants, only one is sick, however sadly its one of the biggest ones.
I had been spraying it with actinovate every 7 days ( since its indoors) ,

saw first sights of pm = sprayd it once in 3 days =
PM shows again= spray it once 2 days=
PM shows again = spray it once a day
PM doesn't show on fan leafs anymore bud goes to bud leafs. FUUUUUUCK

I cant do sulphur burn couse is not in a concealed room and i live there .

If my other plants would get sick i srsly would flip, but i sooo dont wanna cut it just out it has so nice big fat nugs...

pls any advice would be good at this point

3. Pm first showed when i started aplaying molases to the plant. Can that be a reson?

+ Room tempreture = 23.1 C
Humidity 42- 48
And i have 2 big fans.

Only problem i see is grapes close to my window who might have pm but i have removed them to an extent i cant touch them anymore.

1- yes, dumbass molasses.
2-likely you need a more reliable way of measuring and controlling humidity and temps day and night,
mold is difficult to grow at 48% RH in 23.1 c
grape plants have pests and mold, windows let them in when opened.
sorry this happened to you. better fortune next time

How does molasses make it worse? Should i stop feeding molasses to the 2 healthy plants i have left?


+ i believe when i considered baking soda the flaw was that i cant spray it at flower, wich i really needed to do.

Do you feed and foliar silica?

Why can you not spray in flower? Think the rain stops outside. Your spraying pHed water. Just mist with it. Works great on my Cucumbers. Milk also works.

potassium bicarbonate works better than sodium bicarbonate ime, but neither eliminate fully but is your best bet in veg.

Prevention is key, once you get it, it's likely you'll never get rid of it, though some claim you can I suspect they sell for profit and only remove the stuff they can see (that shit tastes nasty and you aren't getting it out of your flowers)

No just molases + fert



I think i read somewhere that if u use it right till harvest u get bad taste+ stun buds if u use it extensively right on flower

If you have had it before. Prevention seems to be in order. Look at using milk.

I found that silica foliars through about week 3 of flower and soil feedings all the way to flush seemed to make it easier to eliminate or keep under control. Its not foolproof but it seems to help. More airflow also helps, I usually lightly exfoliate in late flower--just the big fan leaves that touch each other usually. Basically just minimize the ability it has to gain a foothold as much as possible.

Unfortunately if it gets too out of hand mildew hides basically everywhere. I eagle 20d my basement and it still came back, it took a year or so to totally eradicate it( at least as far as I can tell). You just gotta keep at it. There are a few sprays you can use up until flower, I think flying skull nuke em is one of them although I've never personally used it.

Green Cure (potassium bicarbonate) like @CannaBruh mentioned should knock it down and keep it at bay until harvest. Mold spores are inevitable & are everywhere like on your clothes, shoes, in the air, etc. You cant escape it, but you can control its living conditions. My advice would be to get your growing environment in check. It seems as though you are providing a good environment for it to keep re-appearing. Best of luck!

Keep your night time temps at 77F and humidity under 50% and the PM cannot thrive and multiply .

You could also try a UV zapper bug light during daylight hours as they have been known to repress/kill mold pm spores but may damage plant tissue if you have a powerful one. ATAK RTU works well too!!

Sulpher burners used in conjunction with ATAK RTU every week and humidity lower than 50% with night time temps over 77F will eliminate PM. Sulpher burning should not be used longer then 5 weeks during flowering.

I FUCKING HATE THIS SHIT. Now i spent about 60 e. to Buy a Fungicide called Actinovate, why actinovate? cause i wanted to keep using it until very late of flowering TO MAKE SURE SHIT DOSENT GO WRONG! but what do you know PM IS BACK AGAIN.

Now I have 5 plants, only one is sick, however sadly its one of the biggest ones.
I had been spraying it with actinovate every 7 days ( since its indoors) ,

I cant do sulphur burn couse is not in a concealed room and i live there .

If my other plants would get sick i srsly would flip, but i sooo dont wanna cut it just out it has so nice big fat nugs...

pls any advice would be good at this point

I can help test your healthy plants to make sure it is not infected with PM. The only requirement for our test is a small hole punch (4mm) and our test takes less than 2 hours. DM for details.

Why would I need you to tell me I have something I can visually see? If one of his plants has pm it's very unlikely they all don't unless his strain has a genetic resistance.

The answer to his problem is environmental control and proper preventative measures. Not spending money on a test to tell him something he already knows.

Just because there's science there to detect it doesn't mean that it has to be used. I'm sure most people can tell when they have pm without a hole punch and a fistful of cash.

Since you said "again" PM is in your area. That means that short of stripping down every time you go into your flower room, you're likely tracking more in. The spores will continue even if you're spraying. You can clean the room, keep your RH below 55%, lots of airflow, spray whatever you want, but it will still be around and likely attack your next crop.

I have it all around me outdoor where I am and fought it for a couple of years with baking soda, milk, both worked to a point but it would still come back.

The only thing that stopped it cold in its tracks was maintaining my environment (<55% RH, lots of airflow) and burning sulphur in the room once in a while, generally quarterly now is taking care of it. That kills everything in the room (empty your room, burn for 60-75 minutes) let it dissipate and put your plants back in. Done.
