It looks as if your plants are in early stages of 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.
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.
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.
Good luck and hope this helps you to control the pm.peace

Listen to this guy...he knows his shit. You can also spray them with a well dilluted hydrogen peroxide solution. I was not sure if it was powdery mildew or not so I did not want to steer you wrong. Thanks Lime!

Id agree on powdery mildew. Never had it on cannabis but had it on watermelons and tomatoes. I used a product called microbial.

Osc.fans will help circulate air around to avoid it from spreading and getting worse...once treated.
