Can this Blueberry be saved?? Please help, she's all i got

this mom of mine went through some stress a month or so before flowering. ever since i've been battling with this white mold/powder mold? it went away and think i've come to terms with plants have diseases. my cotton candy kush thats right next to it has never developed the mold on the leaves. should i cut my losses and just put her down? i have a lil over 2 weeks left. the past month i've been spraying NEEM OIL on the plants every 7 days(figure if it can't stick to the leaves it won't stay). i've looked up the urban legand of using a sulfur spray, but know good info i can find....... :sad::wall:

pinched this off google;)

Powdery mildew spores float in the air and are everywhere. They need the proper conditions to germinate: a surface that contains nutrients on which they can grow, temperatures over 60?F (16-20 C), high humidity and a slightly acidic environment. Once the spore senses these conditions , it germinates, sending out a hyhae which seeks out a stomata. It enters the tissue and lives off its nutrients, eventually killing the tissue. The downy mildew powder you see on the leaf is the reproductive organ of the plant, which is releasing spores into the air.
Once the spore germinates, it survives in a wider range of conditions. Lowering humidity does not eliminate the infection. There are several things you can do to eliminate it:
Plant Shield is a foliar spray which kills many types of foliar and root fungus. It is not a chemical but a microbe, trichoderma harzianum strain T-22, which feasts on the fungus. It is totally harmless to non-fungal organisms so it is safe to use. It takes 2-10 days to control the disease. It is available from ITS: 800-375-1684 or 303-661-9546.

Neem Oil is available in many formulations. It is quite effective on powdery mildew, with results noticeable in a couple of days. It is available in garden shops, nurseries and the net.
Armicarb or Kali-Carb are made from potassium bicarbonate. Potassium is a plant nutrient and the bicarbonate makes it soluble and alkaline. Powdery mildew cannot grow in an alkaline environment. The mold dies.
Baking Soda, bicarbonate of soda, is a home remedy. It contains sodium so using it too often will be harmful to the plant. Use one tablespoon per gallon and spray the leaves thoroughly.
Alkaline water controls powdery mildew. Use a water with a pH of close to eight. Some western waters have higher pH. The pH should be lowered to the low eights. The pH of acidic water can be raised using pH Up, available at garden shops.
To prevent recurrences, lower the humidity in the space. The humidity goes up in the evening because as the air cools the air's water-carrying capacity goes down. The same amount of water in the air results in higher relative humidity at lower temperatures. This occurs when the lights are off, a favorite time for spores to germinate. To prevent this, use a dehumidifier, which pulls moisture from the air resulting in a lower humidity.
 
it's at the end of the light cycle in 2 hours and the temp is a cool 70f and 28%humidity. just got done examining the plant that i let my friend tie up and most of the mold is where the buds where touching. i'm going to grab some of those microbes tomorrow. any local hydro store will have that right?

Powdery mildew is the most severe problem there is !! once you see it on the outside its too late harvest sooner and get rid of that sick plant before it ruins your crop! Here is a quick article out of a book I have by Jeorge Cervantez.

try to refrain from spraying anything on them.and if that plant gets any worse get it out of there.Stop the neemoil,its not killing it and buds will taste like crap.Best bet by a longway is to have a dehumidifier in their so moisture is not in air to start with.If not blow a couple of os fans on the plants.
non stop, mold hate fast moving circ dry air.

but im like 10 days from harvest...picked up the seranade..and found out a sulfur burner would really help prevent int the future...but the seranade seemed to work well but smelled shitty..

i know it sucks, but be prepared to taste that seranade if you spray within a week of harvest. i had to chop two monsters that went hermie two nights ago, beautiful plants but i couldnt let em pollenat the rest of the plants. sorta the same i suppose. you could use the buds to make a ton of bho i suppose???????and my last harvest i ended up ditching two skunk ones because they had pm so bad. got em out of there and saved my other 5 by doing so. if you have it now its possible it may come back in the future. be sure to clean every inch of your room with a 10% bleach solution. especially your fans. dont give it a place to start. good air ventilation/circulation, good lighting, consistent temperature during lights on/off and humidity in check. and lastly keep the room extra clean!!!!!!!! next one will be better!!!!!!
