Leaf Problem: What is that shit? (better pics)

I posted another thread earlier, but the pictures were horrible, and the root of my problem wasn't clear. So i've got a bunch of clones and a few mothers who over the last few days started doing this:

I looked around and it seems that A) there could be spider mites, especially noticing the very shiny coating on some of the leaves, but I see no other signs.
B) Could it be root rot??:confused: I hope not, and that wouldn't make sense since they're on a pretty tight watering schedule, between 100-150 ML's of water every other day.
The soils pretty well mixed, sunsoil #4 w/ an added 20% perlite and maybe 5% worm castings. The soil feels pretty normal, but that's why I'm asking the advice of any experts :D thanks

Below i have attached a diagram of disorders, find the one that mosts looks like yours and u will know what is wrong.
