Shiny spots but there is no claw!

[tifer]

Hi!
This is my second grow. They are in veg week 5.
A week ago, there were little shiny spots in leaves. So i thought maybe it is nitrogen toxicity. and i got them flushed with pure water. But the issue is still ongoing, and actually it is getting bigger.
Also i checked shiny leaves if they are sticky or moist, but they are not. they are like other healthy leaves!
Photos in attach...

i used advanced nutritients grow,micro,bloom and also b-52, cal-mag and vodoo juice so far.

i have 9 plant in my indoor garden. Proglem started with 2 and now the third of them got sick. i dont know what to do. if it is contagious, i can throw them out. please advise! thanks for answering already...

does it wipe off or smear at all ?

could be powdery mildew. have never gotten it so have not seen first hand on cannabis yet.
there is a possibility of predatory damage. little closer look would help. my money is on the mildew tho.

thanks for answering. actually , dont think that it is powdery mildew. maybe it looks like it because of light reflecting. here it is the photo of without and with light (same leaf)

have you gotten a loupe or other magnified look ? that would be the next step.
get a look all over the leaves with a 30X magnification or there abouts.

that would help rule out mites or other predators. i would look for microscopic bugs and their eggs.

No i didnt before. But now i ordered magnifier. i wil look into it! thanks.
beside from the bugs, is there a chance that this is some sort of deficiency or toxicity?

shiny leaves is usually from a secretion the plant produces as a defense against predators sucking juices from the leaf.

it is possible that is what is happening. i don't really see a pile of other damage i would associate with that though. i don't see much for spots or other sites where predators may have been.

i isolated those 3 from others. And i will be looking with magnifier. i hope that it is not mite,bugs or something.
