Okay so ive been reading around trying to figure out what this is, its only on a couple leaves of each plant, I have searched the underside of the leaves and I have no mites, I really cant figure out what else this could be, overall they look healthy. Please excuse the low quality of the pictures, the only camera I have is a webcam.

Okay so I left out a little information...

They are in Fox Farm Ocean Forest Soil, mixed with 20% perlite to aid in drainage.

I use PH adjusted 6.0 distilled water.

They are under a 250 watt MH bulb for veg, switching to HPS at flower.

Umm I think thats it.

Anyone out there have any clue what this is? the new leaves that are forming have a couple of these dots on them too, and again I cant find any mites on them.

I have almost the same setup and I am having the same problem except to add to that the temps get up to 110 and one of my plants is really droopy, but the other one is doing fine is the same room?? Can anybody help us??

So these spots seem to be getting a little bit worse =/

Anyone have any idea what I should do about this or if I should even be concerned about this?

I think you may have leaf miners, buddy.
Look it up, but that's what it seems like to me.
They're pretty tiny and they live inside of the leaves, so it's unlikely you'd see the bugs themselves.
I would start a pyrethrum or neem regimen.

I hope your right on the nute burn phyzix, I am waiting for the pots to dry out almost completely then I am going to flush with water then.

I really really hope you are right though, my plants are only 15 days old and the first and second set of leaves is already starting to turn a yellowish color, and I really think the plant is too young to lose those bottom leaves, it only has 5 nodes developed so far and the side branches havent started developing much yet.

and now baaamalaaam thinks its leaf miners >< I hope its not bugs, and I really thought I was bug immune since im indoors.

EDIT*

Okay I just looked up pictures of leaf miners and I dont have any of those lines that the leaf miners create so I really dont think thats the problem. It is more like small yellow dots around the edges of the leaves.

it looks like a problem i had, i had the saime problem all over the leaves, it was where i had spraid my leaves with water nutrient mix and as the water evaporated they got nutrient burn, in little specs all over the leaves.

@Parsley. Why are you letting it dry out? not typically the best idea in what I think is soil you're in? also, if you're going to flush then why wait? I wish your pics were better, its kinda hard to see. They do look like nutrient issues though.. Wait.. what are you feeding them? you didnt mention anything. How old are these plants? they look old enough to be getting some basic nutes given to them semi-frequently.

@zeus wtf?! 110? dude.. that is NOT recommended temp at all. whats your cooling situation? whats your exhaust situation? you need fans. there are other threads for that though

don't plants stunt their growth if you over water them? i alway's let the top of my soil dry out before i add water, i've been told to do that a couple of times. :/ if im wrong im sorry, but this is just what i heard

yeh, i think the top 2" is a decent test.. but doesnt account for water pockets. do you do a weight test? seems like I've read a few things about not letting the soil dry out - maybe thats completely vs what you're talking about. i've been told that too -- water, feed, off a day or 2, water, feed, etc..
