Have you been misting those plants? Bad idea. It may just be the pics quality(for your sake i hope so) but it looks to me like you got yourself some powdery mildew or something btw. Misting during flowering is also a good way to get bud rot.
it looks good. real good.
there is nothing wrong with misting your plants man... think about it when a plant thats outside goes into flowering it get rained on, and depending on where its being grown it could get rained on lots, i have been misting my plants during flowering for over 5 years now and have NEVER had moldy bud, if your going to mist during flowering just keep an eye on your humidity dont let it get to high
