Outdoor plants completely purple? crazy mold! pics

I am attempting an outdoor grow and currently have 20 or so flowering females. I'm experiencing two problems

1)about three of the plants are totally dark purple and dont smell, and another few have some purple hues to it. others though look relatively healthy which makes me suspicious of it being a nutrient deficiency, since wouldnt the majority be affected?

2)my plants are being attacked by mold. im pretty sure its because of the high humidity and off and on rainfall the last week, it was unseasonably wet lately. however ive been ripping off moldy buds and im kind of getting frustrated as its turning into a small percentage of the crop, seeing as i have about 1-2 weeks of flowering left how much should i be worried about the slow creeping spread of the mold?

-also, is there anything i can do to prevent mold or slow it down, something i can buy? i obviously cant control the humidity outside though it seems to be getting better

also i forgot to say i fed them nutes all through veg and at the beginning of flowering, but i used this pellets type fertilizer that was extended release so i didnt want to over-do it, bad decision. i havent used nutes in about a month and a half and im not sure if i want to start using them now for the last 2 weeks of flowering
they started showing signs of flowering august 2nd (8-9 weeks)
it is just bagseed

purple is good! it's just because they are cold.
mold is BAD! u need to get a sulpher based spray and use it immediately! and re treat if necessary. the sulpher spray will raise the PH on the surface of the leaves makein it unlivable for mold spores.. i will try to look up the spray, but maybe someone will chime in and help out?

BTW the mold is powdery mildew, so look up a spray that cures that.. it will kill your plants in 2 weeks u need to get it right away and the plants will recover by harvest.

i agree lolipop a cold spell will turn plant purple thats good let it ride dont over fert and treat 4 mold

when r u gonna harvest

here dude, u want something like this, its called: Nature’s Answer Natural Fungus & Bug Killer
Nature's Answer Natural Fungus & Bug Killer: Natural insecticide and fungicide for use on roses/ornamental plants
Good luck. U will definately want to use a natural product, just rinse the plant down real well after treatments are done, right before harvest and u will be fine...

thanks a lot, i appreciate the help
we have had a cold spell as fall approaches here in maryland
temperatures have hit 45 at night 65 daytime so it makes sense that the plants would be affected by climate (especially since they are bagseed brought in from wherever)
so ill disregard the purple problem


but really i needed that answer about the mold it saved me a lot of time and bud! it really was beginning to be a problem and ill definately follow up with the spray asap

and 007 idk when im gonna harvest. the first males started showing clearly july 1st, so they have been flowering over 8 weeks now. i grew from just good mids i had from a guy in the area so idk how long these will take to flower but they honestly are far from done imo, the trichomes are 100% white though the buds are forming to a point of many low branches breaking (i have solved this problem with intertwining fishing line)

im kind of irritated really about the long flowering, but they do what they do i gotta just let them go

just be patient, those buds are still gonna put a lot of weight on in the last two weeks. if u treat for mold u will be a happy owner of a lot of bud.

I treated and the buds are definately looking better. I used vinegar and have been applying it every third day. thanks a lot for the help.
