Tiny Black Dots

Have about 12 young plants, about 4 weeks since getmination, topped one week ago.
My set up is as follows:
Plants in solo cups, hokes drilled in bottom, royal gold basement mix.

Light is a sun system lec 315w 120v.

Closed grow room, no intake or exhaust.

2 circular fans on low for circulation.

Botanicare Kind nutrient line, feed every other watering (water,feed,water,feed, etc)

Temps are 72-76 daytime 60-65 nighttime, rh stays between 20 and 30. (Dry climate)

I noticed yesterday tiny black spots on my leaves. I cannot find any evidence of bugs. This is my 3rd year of growing and probably my 10th grow. I've defeated spider mites, fungus gnats, powdery mildew and nutrient defencicies throughout my growing and it doesn't seem like any of those. Pics attached including ones at 50x and 200x zoom.

Got em to upload. Any and all help much appreciated. Also forgot to add that I applied a foliar treatment of azama just in case it is a pest. I usually use azama every week or two in veg as a preventative pest control.

I usually use azamax, i own captain Jacks dead bug but rarely use it. It's snowing and winter where I live and I didn't think spider mites could survive outside. Since they are seeds, if it is spider mites, I'm guessing they only could have come from the soil, which if that's the case why would it take 4 weeks for then to show signs of their existence?

Yea you have spider mites and thats their poo...
what pesticides do you have?

:lol: ...she said poo. bongsmilie

Make sure to wipe the tent floor and walls down too. I like to pay particular attention to the flaps that cover the zippers. Shit likes to hide in there.

no no no...bugs have all kinds of ways to enter your grow. Bugs also become immune to pesticides especially spider mites. They carry the immunity on to their offspring. Once you have spider mites you have to keep treating well after they are gone and switch up the miticides on a weekly regiment. This can be an easy fix for you in this veg stage. Get avid, your azamax and forbid and dunk your plants in it. Mix up the proper levels of water and miticides together in a gallon bucket. Clean your grow space and Spray your grow entirely with the left over mixture. Then use the rest of the mixture weekly till its gone. Then switch up your miticides from there on out till they go into the flower cycle, you may spray upto 2 wks into flower then no more pesticides once trics start.

Elvis I'm leaning towards thrips as well. I am thinking that if it were spider mites I would see more evidence than just poop. I see no spider mite webbing, spider mite eggs, or spider mites themselves. I will treat woth captain Jacks tonight, wait a day or two, then update yall. If that doesn't work I will try your mix diabolic.
Thanks to everyone for the help.

Oh and in case you want to take pics that zoomed in, I did so with a cheap 20 dollar usb microscope.

Ok so I just finished my morning inspection. Definitely not spider mites. Saw one bug, looked closest to a thrip. Although it didn't look like an adult. It looked closest to the next to last picture of thrips Dumme posted. It was not that translucent, more of a solid yellowish brown color. No wings. Saw it crawling on top of a leaf. Do yall still think it's a thrip?
It was too fast for me to take a pic so i squashed it.
Sprayed all plants with cold water, allowed to dry under lights, then sprayed with captain Jacks dead bug at 1 tablespoon per gallon of water.
Didn't see any eggs so I'm praying just the one found its way into my grow.
I am kind of confused though because it's been snowy outside here in CO for the past week almost, idk how bugs could still be alive outside. Aren't bugs dormant in the winter?

dude, ive been around the block a few times.

its thrips man. those pics above are good but just a guide,my thrips I usully get look more white like sawdust sprinkles. white residue or leaf damage from suckling is one sign and black specks is second.

follow up with Captain Jacks in 3 days top and bottom and lights off.

Yea I'm on the same page as ya now elvis. So 3 days and captain Jacks again.

One more thing, I was planning on transplanting soon, the lil gals are about as tall as there container now, and I starting to see new growth now that it's been a week since topping. Should I wait to transplant until I do a second treatment? Or can I go buy my bags of royal gold tupur (my preference soil mix)
