Its going to get WAY worse if you do not take care of it. I am having the same problem now but finally stopped being lazy last night and did something about it. Since you are in flower, I would not suggest spraying neem on them as it will make the plant taste crappy. Skim milk 10% and the rest clean water. Shake it up nicely and go to town on the leaves with the infections first. Mold has spores and likes to stick on crap. If you can.. I would totally clean the room its in with rubbing alcohol/water in a spray bottle and wipe everything down. Of course clean up after using the water/skim milk trick. Do not use regular milk either! A hour or so later you will see your leaves beautiful and shiny. The mold on the leaf will turn into a crust which destroys it.

Enjoy.

oh a few other points.. When you spray, turn off all the fans and make sure the lights are on. This really makes it stick perfect! Takes 5 minutes to spray and I would suggest a minimum of 5 minutes before turning back on the circulation. Also remember this is a good bandaid for the mold, but not a resolve for the future! I am in 4 weeks flowering by the way

3 parts water to 1 part fat free milk. biological control of PM. milk has antifungal properties in it.

Soak the leaves both sides, get all the stems too. clean your grow area with 50/50 hydrogen peroxide. pay close attention as your grow progresses and re-spray at first sign of PM. you can see it when it first starts if you look with the ligh coming from behind you as you hold the plant in front of you.

i guarantee you it will control it, the trick is to get your exhaust and humidity under control to prevent it in the first place. nightly inspections and repeated spraying also is needed, but i inspect nightly anyway so no biggie.

good luck! keep us posted.

Dont spray or water inside your grow area, i pull mine out to prevent any overspray that can supply mildew with a place to grow. just an afterthought.

BTW, i just harvested and my starts had PM.... no issues with my buds at all using milk. plants loved it.

:bigjoint:this is the stoppage of all mildew growth, mix up a bottle of bakeing soda and water.. saturate the plant at lights off. this will dry to a fine powder and stop all mildew growth now and help more from being formed from within.. what the bakeing soda does is change the ph on the surface of the leafs to retard the mildew..
i personally done this at first signs 2 weeks in and all new growth looks great and most of the soda has fallin off.
and there is now nothing but a 100 percent healthy plant good luck:bigjoint:
