Clear crunchy bubbles on leaf stems. Egg sac, wax scales?

So I’ve just noticed a few of these crunchy shell like bubbles on a few leaf stems and can’t quite pinpoint what these might be. I’m assuming the worst and that it’s pest related, best I could come up with are wax scales or an egg sac of some kind. I’ve found a total of 3 of these so far, the bubble is crunchy and doesn’t appear to have left a mark on the leaf after I removed it, but really not a clue.
Any opinions or thoughts would be appreciated. I know pics are rough but best I could get

Could just be oozing resin. I have had plants do that when slightly stressed. Yours looks healthy though from what I can see.

When it happened to me I thought thrips eggs - which look similar but they were actually resin bubbles. Yours are bigger but still.

Any stress at all? Root bound or cold or anything recently?

No recent stress I can think of-just flipped to 12/12 about 11 days ago-been a little adjustment to keep RH stable has had swings from 25~50%. I have 2 plants in my tent, have only found on this one, and this one has had some sort of weird wonky issues with the leaves since a baby. I was hoping maybe just a mineral build up from my humidifier, was running regularly until I flipped lights

Its probably just sap. It doesnt really look like scales. Any pest that laid eggs that size would surely be visible.

Have you notice any damage to the leaves?

I had a plant do that when I was DWC in high humidity. For me, it was guttation. It's just pushing out extra sugars. I'd lay odds if you eat one it'll be sweet almost like a honey.

I have had some leaf issues, but it’s the same leaf issue I’ve been battling since this plant was a baby. It’ll start off with maybe a little edge leaf curl, then it’ll get some spots like if you dropped nutrient water on the leaf, it usually just gets crunchier looking in those spots-doesn’t affect the entire plant and it’s leaves, seems to happen randomly on newer growth-tried to rule out as much as I could with that issue, I’ve posted on it several times and haven’t been able to figure out the issue

Since no one has replied with ideas on those leaves.

These spots have me worried and I’d be removing for closer inspection. I’m not sure what it is but leaves can curl around serious issues and the white does not look like spill.1F210198-D407-4FA5-8F1B-14284A242BC2.jpeg


Before noticing that white stuff I was going to say the roots aren’t happy for some reason. It is stressed but I’m not sure why. Any way to get a whole plant pic and maybe pics with the fans off so the leaves are still and clear will help.

Every time I’ve seen guttation (thanks for the new word guys :)) the plant is stressed. I last caused it with nutrient deficiency plus root bound.

I'm thinking bugs. I'd be pulling the most effected leaves of and scoping them HARD. Although if that residue isn't spillage, that's a lot of honeydew(insect excrement). If your camera can do it get some macro shots of the underside of the damaged leaves, that's where a lot of species like to hide.

I second, bugs.

I hope these came out clear enough to give a better picture. I have 2 plants in the tent, the one with questionable leaves is on the right of the tent. Im definitely not ruling out bugs, but I haven’t seen anything definitive to that and I’m also questioning why the other plant wouldn’t be affected if it was bugs.
Only other notable differences is that the problem plant is closest to my intake that has a small space heater placed about 18” away from intake. Also when the plant first sprouted it had a bad case of helmet head, growth was stunted for over a week before I got all the membrane off, cotyledons were yellow from the start and then plant started to take off, but she was growing wonky with the leaves from maybe 2 weeks after sprout. I kept thinking she would grow out of it...

I zoomed in and would you clarify what the fuzzy is. To me it looks like webbing. A.K.A. spider mites.

If I’m not mistaken those spots are the underside spots of the discoloration on the top. So where the rust/discoloration spot is on the top of leaf this is what the underside spot looks like. I’ll try and take a closer look at these spots again, but when Id check the leaves that fell off with these spots under my loupe I didn’t notice any webbing.
Do spider mites weaken the leaf itself? Aside from them looking ugly and problematic the leaves seem healthy-they don’t accelerate and die within days, stems are strong when tugging, have only lost lower canopy leaves and pretty sure that’s from my light

Great job. I see the bug too, on the lower part of the leaf stem. The pic is blurry there but I think the bug is flipping us off.

Looks nutrient related to me with the new pics but I’ve not encountered any of the really tough baddies yet.
I’ve had fans cause what looked like nute burn but that’s usually more uniform or worse where the air source is.
That it’s always had issues makes me wonder if it’s just a trouble maker with misfit genes. Otherwise your plants looked happy AF and growing fast. Wish I was more help.

I saw him too, he's just not a spider mite. Too big. Kinda looks like a predator. Just can't get a clear shot of him.

Actually that black fan you have above canopy pointed down at it does not oscillate? Then intake air too. Honestly thinking you’re on to it with wind. If she’s transpiring too fast it’ll look like deficiency or burn.
Actually hoping it’s simple anyway.
