Powder Mildew Advice Needed

I use milk and remove them from the big hid lights. i spary till they are super soaked. turn a fan on them let them dry. then repeat. put back in room and next day take out and repeat. i do it for 3 days then all mold/mildew is gone. now you can run the last 5 weeks. but fans are huge you have to have air movement my plants bend form my air flow. mold cant grow when air is moving so fans fans and more fans. at each level. my floor has air movement all the way to my ceiling. each fan is on low but it adds up i bet my fans are 1k cfm total in a 7x9 area. that does now include intake and exhaust fans which is another 1200 cfm.
You soak them during lights on or off? Also will milk make it smell weird afterwards? Is this is safe when I am 4 weeks into flowering already to soak the buds?

3% hydrogen peroxide, no need to dilute. Spray the affected areas heavily and the rest of your plant lightly, it will not harm then at all. I usually wipe down the inside of my tent w/ a diluted solution of 99% iso alcohol. Its cheap, you can get the stuff at almost any store/pharmacy. No need for sm-90 or other products.
I agree hydrogen peroxide will do the job and leave no shit on you plants.

Awesome dude, just didnt wanna fuck up my top baby colas, half of the top colas, the white hairs seem to be a little fucked up since the mildew, do you think they will bounce back after a few days of the peroxide spray? I am 4 weeks into 12/12

i would do it with cfl lights on no big hid lights i would also move plant to a bath tub. H202 will kill all the bacteria in your soil so if you use that then you have to replace it. Milk kills the mildew/mold and doesnt afftect the bacteria in your pots.

Would covering my soil while spraying with h202 work? Sorry the main issue i'm having is being able to take the actual plant out of my grow box, I dont believe I will be able to carefully take it out until harvest time. So many stupid little issues haha, plant definately got bigger than I expected

you can cover the soil if you use h202. the main thing is if you have HID lights turn the off then spray and let them dry before turning them on. so you dont burn holes in your plant. 1 drop of moisture is a magnifier. you will figure it out. if you want to cover the soil use a white towel.

I did 1% milk, 1 to 9 with water, and it seems to have worked perfectly, afterwards I sprayed it down completely with water, and repeated the process one more time to make sure all PM was eliminated, after the fan dried it off I put it back in the grow box, hopefully I will not need to repeat this process... THANK YOU very much DCobeen for the advice

yw. make sure to have more fans or if your RH is over 45% in flower then i would get 5 lbs of rice bake it at 250 for 10 min then let it cool.divide in half and place in 2 paper bags fold top loosely and place them on diff sides of room. each day take out and bake again to dry the rice. repeat. till you only need 1 bag and your RH is 30-40% for flower. some strains can handle over 50 but most like it lower. this rice trick works and is cheap and easy.

Slang that shit to crackheads and tell them it's really Crystaly
Lmao. the milk will kill it and you can add milk every time you water/feed. the high calcium( cant overdose them with too much). h202 is really for a root issue. I have micro nutes in a few forms. so i hit them when i think they are getting root bound. then i up pot them. if you really want to know how h202 can help??? hit them 2 weeks from harvest with a decent dose(if in pots bottem feed them only). they will blow up the buds. how do i know this?? was 1 of my experiments. what did that tell me? my roots had issues. so now i have to make sure that doesn't happen again. We all learn. Know that 5 generations of the same strain will adjust to you if you take clones from clones. This is a fun way to learn. I am super baked smoked 3 hits from my c99 hash.

so to help get bigger buds, apply some h202 into my water mix when bottom feeding? considering I have 3% h202, howmuch to h202 ratio should I use? And Im 4 weeks into flowering, any benefits to doing this everytime I flush? or just at the final flush at the 2 weeks prior to harvest mark?

starting the last 2 weeks add 1-2 tablespoon per gallon to your water/feed every time. this will help your roots allot and help finish it better. test this with 1 plant. I did and at a friends grow i was helping him with. i grew 1 and he grew 1 both was clones and ran side by side with each other. the diff was at harvest i had 10% more yield as my buds got allot bigger the last 2 weeks. when we chopped and looked at the roots mine was allot whiter and his had some brown(unhappy roots). I have not tried doing the bottom feed earlier like at 4 weeks into flower. I will see if i can test it with my current grow. Oh so you know i bottom feed/water 3 times then top feed/water 1 time. then repeat. that is my current style. I know a few doing hydro who love using h202 into there res everytime. so I bet you could start sooner but i have not tested it. i will mark 1 of my c99's and start doing it even in veg after i pick up more h202.

^^^^ stop playing with milk and hydrogen peroxide.
Okay i am listening? what is your point and why? i dontuse h202 in soil but bottom feeding works and doesnt kill the good bacteria in the soil. Milk kills mold spores dead period. So please enlightening me. I have a few on another site who every 10 days clean there res and they add h202 to start it back up. sure you can pay and buy a few other things to do the same thing, I am curious to how you can say stop playing with them. I am a open book and if the proof is there i will listen. I do know the ins and outs.

I am about to harvest. :leaf:

I ended up being able to go a little longer than I thought using h202 that
spray I mentioned along with the milk method.

Only problem is I seemed to get a little rot along the way which i expected since there
outdoors (and me spraying so heavily might have contributed a little) but there not massive
plants probably only 3 finger buds so its not that big of an issue no white fuzz just some
little grey/brown parts on the inside of a couple buds.

What I was wondering was if the buds with rot should be removed all together or just where
the rot is? Also can this spread after being cut?

I am assuming I should wash the flowers before I hang to dry but i was worried about browning
from doing so?

Thanks everyone.:mrgreen:

I was using hydrogen peroxide and it seemed to work temporarily but the PM got ahead of me. Finally went to my local nursery and they had several products available. They recommended I use this stuff called Green Cure. Active ingredient is potassium bicarbonate. Using 1 tbsp per gallon of water, I coated all my affected plants and it seemed to do the trick. A couple days later, I noticed more PM showing up on the plants deeper inside the canopy. I then did my second application and concentrated on spraying the main stem and the inner leaves. I do believe it's working, and I will now go to spot spraying as I need to. I've heard it produces a barrier on the leaves that works for several days. It's a lot of extra work at first, but it seems to be getting easier now that I'm only having to spot spray. A couple of other things to remember is that you can use this stuff right up to harvest time and it's harmless/non-toxic. It does, however, sometimes temporarily turn the bud hairs a bit brown for some reason, but the hairs grow back to their normal color within a day or two. I've heard that you can avoid this by diluting the mixture by using 1/2 tbsp.
