Mold?

My plants are 4 weeks into budding and have white blotches developing on the leaves. The blotches arent uniform in size or distribution. I'm wondering if this could be mold. I am growing without ferts. There has been dew developing every night and lingering well into the morning. Just wondering if that moisture could be making my leaves mold. It has also been humid in my area. Any help would be great.

I never really have this kind of issue (australia, warm weather) but it certainly sounds like a type of mold. I wouldn't be concerned unless your buds are effected by it.

sounds like powdery mildew...if you have dew drops forming in the flowering room it's to humid......get a Hygrometer and get the humidity under 40% also make sure lights out temps are not falling to low, you need good ventilation and circulation also, Half way through flowering there is not too much you can do.....it will take over and get into the buds...even if they look OK...after you dry them they will be full of white powder.......do the things I stated earlier and also wipe all the visible mildew off the plant with a clean rag....

remember....Preventing is better than Treating....keep your humidity down and your air moving....

I am growing outdoors tho. I can't control the climate. The temp has been falling to High 60's and low 70's at night and the humidity is going to be 60% tomorrow. Also, one day the buds and leaves were really crystally and now not so much. This mildew must be eating my buds. These are my best plants and I would attempt anything to save them. Any suggestions.

I pinched off all the leaves with the powdery mildew on them. My plant is looking good now. Conditions are still favorable for more to develop. Would running a fan on my plant stop the powder from forming?
