mold on fan leaves 20 days inn flowering?

these are black domina strain. im using super natural nutes, temp never gets above 80, humidity is always at 40%. 20 days into flower the black domina started to get this white mold like stuff on the main leaves. now keep in mind i have 18 other plants in there that are different strain. the black domina's are only ones doing this and its not spreading. what is the deal please help dont know never had this problem.. is it mold?? it almost looks like tons of tri-combs

thanks guys

Mold grows in dark, moist places. Hot or not. Dilute some hydrogen peroxide in water and put in a spray bottle 1 TSP per quart. Mist your plants lightly before you turn the lights on and let it go. If that didnt work, find a way to remove the moisture.

Another thing you can do is to mix some high N nutes in water, again a very weak solution, and mist the leaves lightly prior to turning the lights on. It should be enough to burn the mold, but not your plants.

I really hope that helps.

That looks like white powder Mildew. Do you have nutrients open that arent being circulated? This is a breeding ground for the bacteria. Great simple and easy solution....Baking Soda and Water (Lil warm) Shoot the leaves. The Sodium Bicarbonate acts as a disccant and breaks down the Powder mildew. Bad new is your plants got it for life like herpes. The good new is if they dont get stressed you shouldnt see it return. I used it in veg worked fine. Im not sure if its ok to use in Flower, but i dont think it would be to bad.

yes thats mold.

and the reason you have mold is in the background.
that bare concreate floor, is the reason you have mold.

do the peroxide thing, increase airflow, decrease humidity (which is gonna be hard with that concreate floor there)

if your plant has mold, your room has mold, and every plant you ever grow will have mold to some degree

empty the room, cleen the shit out of it, peroxide, then bleech, seal it all with "Kilz" oil based primer with the anti mold mildew thing (im fairly sure i remember seeing it) but kilz anyway
paint the walls and cieling. seal the floor with that epoxy shit you buy to put on garage floors.
your lookin at 3 days work, give or take, less if u can take the fumes.

get an ozone generator and run it on a timer, 15 min on 45 off. place up high away from plants (ozone damages plants, but has a half life of 15min
no they are not expensive

buy any 12" t5 florescent fixture, go online and buy a 12" t5 germicidal bulb. there u go instant ozone generator, total cost about 35 bucks. less if your a smart shoper

Get some SM90 and not that other stuff, your plants look pretty bad

I have used SM90 with good results, goto the local hydro store and ask for it

Good luck, and like the others said increase air flow that what caused me to get mold

SM90 and Ed Rosenthol's Zero Tolerance Herbal Fungacide
are great products.

I'm sure your temperatures drop in your off cycle, rasing
your humidity quite a bit at night, it is pretty common,
just try to keep it clean, and battle with the SM90
and the Zero Tolerance

If it stays like that you won't want to be smoking
the buds.... You're gonna have to really work to get
that plant back to smokeable condition
