That's very interesting. I have not had the rosetting I see online, but can't grow a big leaf with LED. Things that used to grow leaves big enough to write notes on, are just fingers now. I bet half the size.
These observations between us, really do point to something unlikable about LED light.
I will go out on a limb here, and suggest it's that single blue peak. We don't know what blue LEDs have shown blue isn't good, but can wager it's the same single peak stuff. The sun, or cmh, may have more blue, but it's not a big spike of one colour, as we see with LED. I can't think of anything else even worth looking at, to study this.
Smaller leaves, mean small were enough. Big one's come from low lighting. Outdoor I get huge ones, to use dusk and dawn sunlight, in my cold country. It's this overly small, but mainly the thickness, that tells us they don't want everything they are getting.
I have 3000K plus 660, so my blue is actually low. It's that single peak though. The one that blinds us, so is being worked out of the latest office lighting. The double blue (peaks) stuff.

Article about the more sun like spectrum that we could have, and has been around for a few years.
Edit2:
This is the bridgelux double blue (thrive/vesta) in 3000K, vs their usual 3000K LEDs in a few different cri's
While no 3000K has a particularly high blue peak, we can see how the twin peaks give a flatter output. More in the upper and lower 400s, but less in the middle 400s.
The other curve of interest
So the twin peaks isn't going mental on the chlorophyll B production, at the expense of the carrots and purple ribbon (Yes, I have reached my limit)
E3:
There must be a solid reason why blue used in testing, and our LED lights, is having an ill effect. Yet in other light sources... not so much. These recent blue studies are not saying what light source they actually used, but we can bet it was LED.
E4:
The other thing about carrots.. they are red/yellow/orange. It's the collapse of chlorophyll in winter, that leave these colours prominent in many species. We even collect them as colourings. So if you want that purple, in your purple hazy... you need your carrots.
E5:
The purple ribbon must be chlorophyll A. The one we hit with 660. It's lower peak is somewhere between 420 and 440 on our graph. Where the double blue is making 3 times more light than the single blue.
Is anybody getting onboard with what I'm seeing? Thinking about buying a ticket at least?

Bridgelux announces Thrive series LEDs with uniform and broad SPD
Unique two-pump design broadens spectral energy in the blue region and enables the Bridgelux Thrive family to offer a relatively uniform SPD across the human visual range.

That's a fairly robust backing for my waffle. If we spin up the chlorophyll B, without offering the means to unload that energy for use, then we are doing ourselves no favours.
