look's like spider mite's to me. Try a drop of sunlight dish soap in a spray bottle with water and completely soak the hole plant. repete every other day.

The black spots are bug shit. Mites, or whatever, you need to work on pest control. 3 steps I would take after washing the leaves with dish soap as suggested. You can just wash them once, then:
1) sprinkle diatomaceous earth on the surface of the soil. This kills insects that live, breed, or land on the soil.
2) mist the plant with neem oil. This kills mites if you have them and protects the plant from further attacks from any insect.
3) put yellow sticky traps around your plants to monitor if the pests come back.

BTW that damage looks like thrips, not mites. Mite damage can be most pronounced on the upper parts of the plant, and the chew spots are smaller. Thrips breed in the soil and munch on low leaves, and you can see bigger chew spots. That looks like thrips. So the diatomaceous earth is your best bet.

go get flora mite, avid, or green lights spray for mites. you need to do this asap. soak the top and bottoms of all the leaves. if your into flower more then two week just set of 3 foggers. one every other day while lights are off.

have to use a product with pyrethrins in it, like "Clean Air Purge III". Also get a dispenser that will auto spray your room.

If it's mites...

it works for thrips too.

i just use bedding spray. it's for lice. the active ingredient is permethrin. it got recommended to me when my snake got spider mites. works like a charm and dissipates quickly. just don't breathe the fumes.

Shake,
What's the name of the bedding spray and does it work for gnats too? Also, what kind of snake?

Had a simialr problem near the tops of my plants. The new leaves had a black substance on them as they were "coming out". I was told that it was a parasite or something and should use seven dust on them. Problem went away in a few days.
