Hey man! I recall you helping me in the past! Are you saying these could be trichomes? My brain is spinning in circles trying to decipher what's what with these white specks on the seedlings and the tan spots on those two leaves.
Plant Glandular Trichomes as Targets for Breeding or Engineering of Resistance to Herbivores
Glandular trichomes are specialized hairs found on the surface of about 30% of all vascular plants and are responsible for a significant portion of a plant’s secondary chemistry. Glandular trichomes are an important source of essential oils, i.e., ...www.ncbi.nlm.nih.gov
Please help me identify what these spots are

I would say don’t sweat it and update how it looks a week or so later with nutrients. Their bound to need nutes in 2-3 weeks from sprout and they usually mean it can feed off its cotyledons through germination. Theres a lot of stuff out there that users here would beg to differ, don’t be surprised.
I shouldn’t speak on rdwc I just could of sworn people would feed nutes right away or expect some leaf signs to arise which is when they start feeding. When I fed plain water I once got good growth for a few weeks my very first coco grow but the very next it needed nutes asap.

I would check for bugs just to be sure but looks like resin heads

Yep. Is your camera flash always on? Its not neccessarily THC/resin at this stage, but could be other oils too.
As for the calcium, maybe your PH is just a little low?

Check out this dank spinach..
Frosty huh?

Now check out these dank resin glands..
Just kidding!
Those are mite eggs.
Hard to tell huh!

That is what I meant by sus! Not a bug identifier at all but they kind of looked like that but too blurry to tell.
I know it's blurry but here's a zoom in on one of the pics I posted. When zoomed in the upper area white specks start to turn into droplet looming things.

No the flash isn't on. Should it be?

Mites don't usually lay eggs on the top of the leaves anyway.. Not that they won't. Even if they did, you would see way more leaf damage\spotting along with that many eggs. I would expect to see bigger spider mites crawling around for that many eggs that size too. I don't see any sign of mite damage btw, just trichs, which I thought were extra shiny due to some light source hittin them just right, possibly your camera flash, making them stand out more. I would freak out at first glance too, and think they're eggs.
Your plant was bred that way IMO, carefully selected for those traits, which could potentially give it extra resistance like you say..
Shouldn't be that hard to tell they are glands.. try to scratch a few off. Rub them and smell..

I was starting to wonder if it is early trichs after I mentioned it being pest resistant. It started to click that since trichs are a protective measure, a resilient plant may have them early on to protect itself. I know they rub off because I rubbed that leaf earlier and the spots disappeared. I will give it a rub test for smell. Thank you for all your help man! You have been incredibly informative! Just as you were the last time you helped me.

I'm on my PC too, with a huge 43" monitor @ high res, and I can see up close like an eagle ...but blurry af anywhere after a few feet because I lost my glasses like 15 years ago btw. I feel like if I wear glasses my eyes will adjust and I will lose my microscopic super vision powers that took decades to hone in, lol.
I wouldn't expect those that browse the forums on their small phone screens or whatever to see as good..

Wow! Definately left an odor on my finger! You hit the nail on the head about the white spots! Thank you! I was stressing balls, man.

Rubbing will smash them (and produce some smells hopefully), but I bet if you poked around at one with a needle and magnifying glass you'll find they are connected, and part of the leaf. Just trichs.
I also bet your PH is kinda low causing the other spots, due to calcium not being as available. Who knows, maybe the leaves are being signaled into producing extra oils just because of the calcium deficiency? Either way, I would get on that soon, and make sure your in range before doing anything else. Use test drops in case your meter is off if you can..

I owe you an apology! Your diagnosis about the trichomes was 100% correct. Just rubbed the leaves, as advised by another member, and my finger had a strong distinct smell from the trichs. Sorry I doubted you man!

"Head on the nail" is more like it.
I will get on recalibration my apera ph meter and break out the drops as well.
As for calcium, I only started with 25% of the recommended week one dose of calmag. Should I be increasing that since I'm using ro water? And is it possible for calcium deficiency to show in the lowest leaves instead of upper?
These color range for these drops jumps from 5.0-6.0. It doesn't have 5.5 on the chart. It's reading orange which is 5.0 but I'm not sure if that's because the next color isn't until 6.0 which is green and it's somewhere in between 5-6.0

It's all about interpreting the shades. With the solution I use, orange is 5, piss-yellow is 6, green is 7. You gotta look for a good mix of the two surrounding colors if you wanna be right between them. Takes some decent eyes and time to get used to. I typically guess slightly high, since that seems better than low.
Well then, it looks like my ph is low. This darn $50 apera meter is reading 5.8-5.9 after calibration. I will bring the ph up a lil bit at a time over the next couple/few hours, until I get a piss yellow color. Seems safer to shoot for the piss yellow and be at 6.0 than guess with the orangeish an be low, like it is now. Thanks again bud! Your are the man
