OMG MOLD, MOLD, and more Mold

I am growing hawain purple kush, and purple erkel. Im about done, and all plants are in heavy bud stage,about 2 weeks ago I noticed some white powder mold on the kush leaves, I looked ot the erkel and didnt see mold on it.I have my plants in bedsone side is erkel, and the other is kush.
I treated all my plants with spray, and it seemed to work, but last night I seen that the mold was back, not alot, but enough. I figure I have about 20 days left till I harvest, I was going to get a sulfer burner, but I was told it would mess up my buds, so I passed on that. What can I do to kill this hell mold?

Some people use a scapel or something like it and shave off the mold

milk. ive read many places that a 1:9 milk:water spray is really effective. Old yogurt is supposed to work OK too.

Can you post a pic?

my new pc got took yesterday by my partner, and im stuck with this old pc i have had forever, so I dont have any pics sorry.
but its just plain old white powder mold, its not on every plant, just a few, and only the purple kush has mold, the erkel is fine, its weird. my room is split in to two sides 50 on one side and 50 on the other. its the master bedroom in a double wide modular home. I picked this room for its size, and the walk in closet, that I plan to make in to a clone room one day soon, and most of all I picked this room becouse of the bathroom in it.I have an air conditioner in the room, and I noticedwater was leaking on the floor in the grow room, so my man fixed it by makin a drain that would empty outside, I wonderd if maybe some water was sittin in the bottom of my air conditioner and thats what caused the mold, I keep all watering very contained and whipe up any split water on the floor right away, I put a 55 gallon olive barrel in the shower stall whith a sub pump in it and hooked up a hose, and it dosent leak.
im stumped, I just want to get through this last bit of budding, then I will sanitize whole room, but I still dont know what caused it. I dont want any mold next time.

dont spray the plants with anything! thats the problem they have humiditty, cut away any moulding buds before it spreds to the rest of the plant, i was gonna say fit a dehumidifier, but with the aircon it should be dehumidifying anyway, i have to put humidifiers in my grow rooms to get the humidity back up above the 60% the aircon leaves it, there is no water sitting in the aircon! i asume it is a split unit!
what is your humidity levels in the grow chambers, room?
and i stick to extraction and airflow! even if you have aircon it can have dead areas of air that need moving plenty, some species of sativas and sativa heavy hybrids do suffer with mould, normally the more common mildew, as you say this is white i feel it is more than likely to be a fungas rather than mould! the remedy is a very dry room and plenty of air circulation.

good luck

welcome to the world of endless possibilities,,,,,hydroponics

there is a completely organic product called serenade. you can spray up till harvest. i too hate spraying my buds, but anything is better than mold. if you have 3 weeks left, i would burn the sulfur. i usually quit using it the last 3 weeks, but if i saw it at 20 days, i would def. burn the sulfur. its only gettin worse if left untreated. burning the sulfur should give you a 2-3 week window to let you finish your girls out-w/ NO MOLD!!!!!

Ty for your imput, I hear ya, but the sray I have is holding it at bay, its not geeting worse, I gonna not burn the sulfer this time, I just want to get through these few weeks,This is my first run,I have alot things im gonna change newt time around, im learnning.
