Unusual leaf markings

Pictured below is an Amnesia OG S1. It was the only viable seed out of the five that I tried to pop. She seems to be growing just fine, but these striped leaves are irking me. The other two plants (same mom, different pollen donor [male]) which are growing in the same coco and fed the same nutrient regimen are doing awesome!

The stripes on this girl are yellow, not brown. She has displayed this anomaly since day one, when she first popped her head above soil. The leaves don't turn necrotic, they don't shrivel or die off. They appear to be growing just fine, healthy as could be, but with yellow striping. The other unusual thing about this plant is the stems. They are the hairiest stems I've ever seen. Like sasquatch hairy. Aaannndd... they also appear to be covered in little tiny translucent bumps, almost like a cloudy green/yellow tree sap. I can feel them, but they're small enough that I can't quite make them out without my 10x loupe.

Some basic info about the grow..
4x4 tent
Air cooled hood w glass
Lights on temps around 80
Lights off temps around 70
Coco coir 7 gallon container
GH micro and bloom using H3AD Formula at 1/2 strength at time photos taken with tap water, now 3/4 strength with r.o. water along with the following:
Botanicare Calmag plus at 1 tbsp/gal
Botanicare Liquid Karma at 3/4 tsp/gal
FoxFarm Big Bloom 1/4 cup per 5 gal.
Mycorrhizae
Water is always pH'd to 5.8 - 5.9 after adding nutrients.

I have already checked for pests, there's nothing visible to the naked eye or under 10x magnification.

I broke out the 30x lighted loupe. Then broke out the 100x digital microscope attached to my laptop. There are no signs of any creepy crawlies, tops or bottoms of leaves, stems or growth tips.

I haven't checked runoff pH, I'll check soon and get back to you.

First impression I'd say thrips, but you dont need a scope to see those little bastards, but they hide, so if you've checked it over and saw nothing ( they like to hide in the veins of the underside of the leaf ) ph or temps maybe ?

Double a triple check for bugs.

Keep an eye in these... i had same situation as u ended up being thrips later on. Very hard to see until they are big. Check the bottom growth for any leaves getting crispy abnormally fast.

Runoff is 6.3.

Checked further for bugs and didn't find anything new. I mentioned the bumps which look similar to sap, on the stems, found with the digital scope that they're on the tops and bottoms of the leaves too but even smaller. Nothing is moving and I can't see any legs, so I really don't think these are mites.

I'm still not convinced that this is from an infestation as it hasn't spread to my other plants. Believe you me, I've been thoroughly checking every day. I apologize now for a long winded post. TLDR at bottom.

I have a hard time believing these are mites. First, there are no foreign cuttings. Ever. All the plants in the grow are from my own seedstock, so it can't be a mite that travelled on a seed in a breeder pack. I would think that to be extremely unlikely anyway. The coco is washed and reused from a prior grow and I have NEVER had any type of infestation before. I grow indoors and at the time of planting, I had not been working in the yard yet because it was still winter...much too cold for mites anyway. So they weren't hitchhiking on me. Most important is that the plant broke ground and showed this issue from it's very first leaves. The seedling stem had waxy looking blobs on it (for size reference, they range in size from smaller than trichome heads, up to maybe 2mm or so, many are visible to the naked eye), and now, two moths later all the stems still have them. The leaves have been funky, striped, blotchy, from day 1 and have what appear to have similar secretions all over them as well. Some are transparent like a clear droplet, some are only translucent, some are very waxy looking, some are completely colorless, some white, some yellowish. There are no legs, they NEVER move.

They appear to be excreted by the plant based on the way they are attached to the surface of the leaf or stem.

One last tidbit - this s1 seed was made by me, incorrectly - I flowered a small clone and sprayed the whole plant daily with colloidal silver and it grew male flowers and pollinated itself. I continued spraying after seedset and severely burned the plant. She looked absolutely horrible. I managed to keep her alive long enough for the seeds to mature, but she was severely stressed. I don't know if this is some kind of mutation, passed on by the severely stressed mom, or if the continued spraying of silver during seed development could have directly affected the genetics inside that seed.

Someone, anyone knowledgable please respond to my points above and let me know your thoughts? If you're convinced I have mites, how did I get them? What can I do about them during flower? And why didn't they spread to the other plants whose leaves are totally intertwined with these?

Thank you!

TLDR
I think this cannot be mites for reasons listed above. They appear to be excretions from the plant itself. Wonder if it could be linked to silver toxicity in mother plant or in developing seed?

100% sure? It's painful to think of tossing this plant. I removed her from the tent and she is just sitting out now awaiting her fate. I have about 8 hrs until dark period to make this decision.

Why havent they spread to the other plants that have been touching her for nearly two months?

I’m so sorry to tell you but I can almost guarantee you that it’s thrips. I had this EXACT same problem not as bad but quite similar. With thrips you don’t always see the because they live in the leaf matter and stem and their larvae is in the soil. You only see them when they are mature. I tried everything nothing worked so I had to kill the plant. Unfortunately I’d have to suggest the same thing

Anyone else care to chime in before I chop her down? This is painful.

It appears to be some sort of Guttation. I never heard of it on a leaf before but I'm reading that it's common. Can't find ANY pics of it though.

Like you oh so wisely said.. It has not spread to the other plants. It is not a bug.

Edit: I would actually clone this. Immediately. This could be one of the most resinous plants of all time for all we know. It def isn't under attack from bugs. That is clear bubbles coming from glands. This is called guttation. Clone it asap.

It looks to me like a potassium, or magnesium deficiency, and they are often related...Some plants are potassium whores!! I have one strain like that myself, and I am experimenting with black-strap molasses. Plus you are on the light side with the Cal Mag, especially if you are using RO water.

The first thing I'd do is try upping the cal mag for the plants in question.
