a bad enviroment causes mold to much humidity not enough air circulation i would cut off the moldy section of bud and fix ur enviromentconditions and hope for the best u can still make hash out of it maybe butta but i would check the bud real good before i consume any of it
That's powdery mildew. You can easily take care of that. Lots of people suggest different things, but you can get some sulpher spray for the leaves, or there is something called "greencure" that works really well.
Different strains are more/less susceptible than others, so maybe next year try something hardier.
I also recommend getting a healthy microherd in your soil, and watering with molasses added. The combination of the sugar and beneficial bacteria will help prevent PM as well.

The one time I had PM I threw out the plants, started over and it came right back. So I threw out the plants again, threw out everything porous (rockwool, airstones etc) washed all non porous surfaces with a 5% bleach solution and started again. PM never returned.
Just a warning some plants are just prone to PM lol treat it like black death in your grow..lol peace out Headband707

Powdery mildew

What do I do about mold?
My plants are in flowering on a 12/12 schedule. The problem is a light dusting of whitish-grey mold. I have a very good exhaust system. Will this affect the THC? Is it harmful to human consumption? How can I stop it?

It sounds as if your plants have been attacked by powdery mildew. This is a mildew closely related to fungus. The powder is the mildew's reproductive spores. It thrives in an acid environment in a temperature range of 60-70?F (15-21?C) with a humidity above 50%. The spores are floating in the air and there is no practical way to screen them out. Instead, try to change the environment so that conditions don't match the mildew's needs. This may require raising the temperature or lowering humidity.
There are also several safe and effective ways of controlling powdery mildew using minerals or organisms.
Most of the mildicides listed here are fairly new and they are all much less harmful than the old chemical formulations. You won't find most of them at your local store or garden shop, but they are available on the Internet. Many companies sell them there. All of these mildicides are used on edibles or herbs. Some are naturally occurring organisms and are exempt from registration. Others are registered for use on vegetable crops and are considered in the "caution" category, the category for the least dangerous registered mildicides.
AQ10: AQ10 uses a totally new method of fighting powdery mildew, a biofungicide. The active ingredient, Ampelomyces quisqualis, is a fungus that parasitizes the powdery mildew organism. It offers control over a long period of time.
AdvertisementCinnamite: Cinnamite is an extract of cinnamon used as a miticide which is also effective as a fungicide. It is very easy to use, is effective and has a pleasant cinnamon odor. Studies show it is not harmful to marijuana plants.
Copper: Copper ions inactivate some fungal enzyme systems, killing the mycellium. Copper has been used for over 100 years, and is effective. A few brands of copper based fungicides are Phyton 27, Dexol Copper Bordeaux Mix and Kocide DF. There are many other brands available.
Neem Oil: Neem oil is pressed from the nut of the Indian Neem Tree. It protects against and kills mildew by interfering with respiration and collapsing the cell wall. Some growers claim that plants grow more vigorously when sprayed with dilute neem oil twice a month. There are many brands of neem oil available. Many of them are listed as organic.
Plant Shield: Plant Shield contains the organism Trichoderma harzianum strain T-22. This organism attacks fungi and mildews. It is used as a spray or dip. The organism seeks its food and forms a symbiotic relationship with plant roots, which it also protects.
Potassium Bicarbonate: Potassium bicarbonate collapses and desiccates the mildew hyphae. This is a very safe, very effective contact fungicide. Mildew do not develop resistance to it. The potassium in the formula is absorbed by the plant. Two brands are Kaligreen (registered in California) and Armicarb100.
Serenade: Is the fermentation product of a bacterium, bacillus subtillis, that inhibits cell growth of fungi and bacteria. It is very effective and easy to spray on or to use as a dip. It is a contact fungicide that kills only areas that it contacts. A wetting agent or spreader increases total contact.
Sodium Bicarbonate (baking soda): Baking soda leaves an alkaline residue on the leaves. The sodium collapses the powdery mildew cell wall and the alkaline environment discourages growth. Plants have a limited tolerance to sodium, so the residue should be washed off before more is applied. Used at the rate of 1/2 teaspoon per quart of water with a wetting agent.
Sulfur: Elememtal sulfur interferes with mildew cellular respiration. It has been used as a fungicide for more than 100 years. There are small packages available in the baking sections of supermarkets.
These new remedies make it much easier to deal with powdery mildew. They are all non-toxic and eliminate the problem fairly easily.

Ok everyone last night I treated my plants for the second time with GreenCure and the was not a sign of PM or mold. This stuff really works! I'm going to continue to use weekly in a lighter dose once a week to keep it away. I was ready to give up on my girls and now they look great.
