It is only a guess but it looks like it might be white powdery mildew to me.
Early signs of powdery mildew include white powder/fuzzy patches on leaves (usually low in the canopy) and a fuzzy white coating on lower stems. Note: powdery mildew can be wiped off the leaves for a quick visual check.
Go to the following site and read up on it and see if it seems to be what you have.

I hope it isn’t.

doesn't wipe off, its more like a burn on my leaves its just on the edges, and its in the leaf not on top, looks nothing like pics of powdery mildew.
thankfully I don't think its mildew. phew.
but, i'm going to increase ventilation and monitor humidity levels closely just in case. some of the symptoms seem to match..

Do you have pics with less over-compensaton for contrast(sharpness)? Almost seems like it's a leaf-specific disorder than than a plant disorder. They look plenty healthy otherwise.
Do you get nute water on the foliage? This could be bad. Might be that aquarium splashing salt water. (high salt % absolutely will kill most plants)

Im glad to hear that it isnt white powdery mildew because depending when it hits it can be doom. The pics just looked like it was a possibility and since no one else had mentioned it I figured it might be good to mention it so it could be checked for and if it was it possibly could be dealt with in time.
Maybe the pics were just not all that clear, color-wise, but the spots/areas looked rather white and that is something I have never had happen to anything I grew.
Again only going by the pics it didnt look as much like a burn but instead like I first thought possible, the white powdery mildew, but it also looked like bleaching of some sort but it was localized and normally, from what I know about bleaching, it usually hits entire leaves and is most times from a pH imbalance so that does not seem to be it either.
What sort of reflective material are you using? Could you possibly have some hot spots that could be causing localized burning and or bleaching?
I have heard of some strains that can have leaf bleaching from artificial lighting and especially if there are hotspots where an increased amount of light rays strike some area of the plant or certain leaves.
Have you tried something as simple as turning/rotating your plants of moving them around and see if the leaves green up again? I am sure that is one heck of a LONG shot, like picking a trifecta, but at times the only way to figure something out is to eliminate the things everything you can that could be possible and whatever is left regardless of how improbable it is that has to be your problem so to eliminate or discover the possibility that you have a strain that can suffer leaf bleaching from increased amounts of artificial light from hot spots try rotating your plants or moving them around. You have nothing to lose.
i've increased the airflow and im spraying with a milk solution, I read it works as good as fungicides.
