White furry blotches on leaves??????

Hi,
its my first grow and the plants look V.healthy but they have started to get small white furry spot on the leaves can any help????
Thanks

Could be powdery mildew, ya have pics?

unfortunatly no, ummm..... know anywhere to check for something similar to what my problem might be? i was thinking the may not be able to get rid of all there co2 on a night time??????

sounds to me like you have fungus/mold growth on your leaves, search around the threads for fungus and mold and see what ya fund, you should be able to find similar cases on there.

sounds like powdery mildew what's the temp. range? ventilation?

get some air moving in there and that will not happen. To elliminate it a sulpher burner works best...

Thanks for all the help ppl!!!!

good luck on that man ....good air movement and not to high humidity will do the trick .....try to catch it before it gets worst..........
