Powdery Mildew in very beginning of flowering! HELP!

So I've been vegging for 1.5 months, and my girls just got put into 12/12 2 days ago, under 2 600 watt HPS lumatek lights.


My setup consists of the following:


- 2 oscillating fans, 1 stationary fan
- 5x5x6.5' secret jardin


- 6" Tjernlund fan exhausting both hoods, pulling off a phresh 6x24" carbon filter.


- Have another 4" inline fan pulling off another 4x12" carbon filter


- Been using Botanicaire Pro Grow/bloom/calmag and GO BioRoot.


Was using neem during veg to keep shit away, once every 2 weeks. Went home for break, had a friend caring for the girls, came back to the very beginning of powdery mildew on a couple leaves.


I've been removing leaves with small spots every day! GreenCure is not seeming to help, as I gave them a very thorough spraying from top to bottom.
Neem isnt helping either.


HELP! What are my options? Ive done a lot of research, but Im still lost. Should I try UV-C lighting? I've also read that someone spiked there temps to 100F for an hour once weekly, and this killed the mold.


Please help. I have a bunch of medical plants that are beautiful and I cant stand the thought of bud-rot.

I have battled pm on more than my share of plants using a mixture of water and milk. Some here on riu claim it hasn't worked for them but it has for me every time. Everything else I have tried did not work or would not be a great idea late in the flowering cycle. If you search youtube Jorge Cervantes has a video where he washes finished flowers in a mix of water and hydrogen peroxide. Amazing stuff and supposedly completely effective and safe.

Go get an fungicide that used for vegetables and use half strength. Gradually increase it until the fungus is gone.

fungicides during flower= fucking retard smoke that shit and see what happens. Sulfur burner worst case scenario... organic anti fungal best case scenario mainly garlic oil corn oil pepperoil but affects are minimal best bet for you is keep your night time day time temps under a jump of 20 degrees keep your humidity in the thirties and in the end you can do the george cervantes technique where you wash your buds in h202 water solutuin to rid of pm.

corn meal water; enough to get it milky. i don't know first-hand if it works, but it is touted by some.

was NP for me especially in the beginning of flower, he/she has 2 months to go at least for growth, kill the fungus, then rinse with water once you have your humidity under control. This is the fastest most efefctive way and WONT effect your herb this early in flower stage, Also Bryon209, thanks for the insult, I know that's why i come here! Love getting insulted. I hope it makes you feel o so smart.

its insulting to give miss information and dangerous to put toxic chemicals on weed to be distributed and ingested....if its some ones health or your feelings...hmmmmmm....you seem like you have the right idea apperently if your setup is in the closet at your moms house......fucking lame ass

wow, you have no idea. Have a nice day punk.

spray that stuff one time with eagle 20 and never see pm again. as long as you use it before week 5

just had this problem and tried h202, that didnt work. then i tried baking soda and a lil bit of dawe dish soap and that didnt work. then a buddy recommended serenade (all organic and omri certified) and all i can sayis hell yeah. i was amazed by how quick it worked.i caught it early and am still battling it but its so much easier to control at this point with serenade. you'll want to wear a mask when applying. it says you can spray the day before but imo i would quit using it a week before harvest. make sure that your humidity is 40% with air getting around all your plants. also, when the lights shutoff make sure you get excess humidity out because when temperatures lower, humidity will rise. very important you control this at night and have good ventilation and fans blowing on them at nite. if not, most likely pm is spreading at this time.

I applied a 1:10 skim milk dilution thoroughly to the tops and undersides of my leaves in my tent.

Only time will tell now.

the number 1 way to beat this is (myclobutanil) although you may offend some puritans and hippies by using it
systhane fungus fighter is the same active ingredient as eagle etc but you can buy it anywhere and its not expensive

eagle tends to be sold at very concentrated ratios and is intended for very large crops (outdoor) although you can spend lots of money on it and dilute it for indoor use

systhane is used on fruiting edible crops .. the active ingredient to look for in these products is (myclobutanil)
this product is used in the grape industry too

other products can work but none will work as quickly as (myclobutanil) and with only 1 or 2 applications and its gone

if you want to be more "organic" skimmed milk, raising the ph level with products like greencure, (potassium bicarbonate)
neem oil , sulfur burners,
ozone generators, can all help too

good luck you will need it,
peace

Go skim milk he aint lyin....................http://www.thefrugallife.com/mildew.html<------------------------------------check it

So I had one spot on 1 leaf that I caught. Ive been frisking them every night.

Just dropped $150 on a 25 pint dehumidifier. Hopefully it will bring the humidity down to 40. We'll see though.

Lol if your gonna be a douche at least make sure the thread is not over a year old. That kinda makes you look retarded
