White powdery stuff on leaves (possible fungus/mold?) please experts help!!!

I have 5 plants in flower atm, 3 OG, 1 homebred indica, and 1 Ice

The 3 OGs all have a very fine whitepowder on the leaves...they show up in spots...so the leaves literally look like they have white powdery spots...any ideas of what this is? it is only on my 3 OGs...but it looks like there might be some starting to form on the homebred indica now too... so im worried any help/advice PLEASE?

Just wanted to know, are you using c02?

Does it look opaque and matte or crystalline and shiny?

Opaque may mean mold. Shiny crystals are good.

Its most likely a mold due to inadequate ventilation in the grow area unless thyer just some crizzles forming

well they dont look like normal crystals that form on leaves if thats what you mean, its actually forming on the older leaves now that i look at it the oldest biggest fan leaves

its more opaque then crystally though.. like a fine fine powder

and it is appearing in spots that are like 1/2 inch in diameter
