They are incredibly small and are probably thrips. About 1/10 the size of a grain of rice. Tan to white in color.
The damage to the leaves is only on top. I see nothing on the bottoms of the leaves such as black dots white dots or anything that looks like eggs. no webs.
It looked like powdery mildew at first until I took a 40X look at them.
I may have caught them very early and have been spraying the not yet flowering plants vigorously with a Dr Bonners soap solution. I may be seeing only the larvae and no adults.
The flowering plants on day 60 or more I have just been hitting the leaves carefully.
The damage is not that bad, but "they" are on every plant but the seedlings.

Questions are
Should thrips or mites should be treated in the same way?
I have plants almost ready, some seedlings and a few in between. What should I keep or just throw away.
What about the soil? Get rid of it too?
Clean the room obviously. Keep a positive attitude. Is there anything else I can do?
Tell me the worst. I can handle it.

I'm not going to get upset and blame it on the universe. I screwed up somewhere probably not following my own advice. Hands on continuing education. Yea, that's what I'll call it.
 
Pictures? Shiny spots on the top of leaves? Thrips are a bitch but slowly fixable. Daily soap will work. I like lost cost plant therapy. Can be used until day of harvest. Thrips take a while to get rid of since you pretty much have to kill all the adults, wait for the eggs too hatch, and then kill them
 
For starters can you get us pictures?

And how close are you to a store that would carry some basic IPM solutions?

There are several IPM sprays that are relatively safe to spray in flower (I say relatively because there's an argument to be made about spraying oil-based-anything in flower, but many growers use them at home and they are even used commercially BECAUSE they are so effective and BECAUSE there is no discernible effect on the finishing flower.

I'll second Lost Coast Plant Therapy, the three main active ingredients in it are soy oil, peppermint oil, and citric acid.

Doctor Zymes is another popular product used in flower, which the main ingredient is citric acid.

Make sure you're reading on the labels if they are a CONCENTRATE or RTU (Ready to Use) !

You can find "home brew" versions for most of these things as well (very easy to make, very simple ingredients!)

You -have- to do something though; ignoring it solves nothing and will destroy your crop.
 
Captain Jacks dead bug brew aka spinosad does amazing work also what the others have said also

so very tiny to get a decent picture. The leaves are only damaged on the top but not shiny. More like white blotches with some towards the edges of the leaves.

Great advice and I have been proactive with the spraying and scouting.

All of the soil that is not being used I put outside in the freezing weather until I know what to do with it. Every tool, twist tie, fans not used etc. is out of there. I got some scrubbing to do.
Do you think I should scrap the seedlings and just finish out the 60 day or mores?
Two plants are 33 days and beginning to flower. I would be sad but if they got to go that's that.
I wanted to try a perpetual grow not a perpetual problem.
 
That's a pretty legit infestation. Gonna take 2 weeks of treatment. Thrips are sap suckers so you want to focus on the plants more then the dirt. You can probably strip the leaves off the oldest plants and that should remove a good amount and spray every inch of the plants and keep the fans turned up. Spray the tent and equipment and outside of the pots with iso. As for the extra soil, you're gonna want to cook it to kill the eggs. Putting it outside in the winter will make critters go dormant but they'll wake up once they warm back up
