That's oozing. It's unconnected to the previous section, but dripped out after the movement. The first blob attaches a little outside, the second blob on that one, building a 45 degree spire. (One crappy side effect is that for REALLY long moves, it can cause under extrusion at the restart.)

I have a Sovol SV06 Plus, also high flow. Same issue. I think it's a weakness in all high flow because there's FAR more filament in the melt zone. Lowering the temperature has helped a ton, but not solved it completely. I added a bigger fan on the hotend cooling section and it helped a lot, but not solved it. I've been told that upping my retraction to unreasonable levels should help, but I've not tried it. As in, I've got a direct drive, which usually has retraction less than 1mm, but to up it to 4mm. It's my next experiment.

As an aside, if I could go back, I'd not get high flow option. I'd stick with the standard SV06.

I actually had a hell of a time with petg with a 0.6mm cht on a dragon hf, ended up going back to a nozzle x because of it. I also found the bimetal cht nozzles really fragile, like 1.5 Nm torque from one of those slice preset wrenches and I'd still manage to have them shear off in the block after a few nozzle changes.

What did help was lowering the temps and being aggressive with the retraction speed (went up to 50mm/s if I recall), but even then the cht nozzles oozed a lot with petg, could have tuned a bit more but as I said I ended up going back to my other nozzles.

Kept the dragon though and actually swapped my mk3s over because I like that the block is fixed for nozzle changes and actually changed my voron to a dragon UHF that seems to be working well so far.

Some of the PLAs that are matte like this, are in my experience more prone to moisture absorption and all the related problems.

I had bad stringing with some modified PLA, and drying the filament completely cured the issue.

I've had those on PETG. It's not really stringing, it's a little tiny drop of filament that gets deposited further and further out as the nozzle makes travel moves. They clean up easily enough, so I've never worried about trying to deal with them.

That said, have you tried a lower temperature?

With a cht you have to be carefull of not retracting too much. I generally use 0.2 to 0.4 for direct drive. Higher travel accel can also help minimise strings.

have you tried turning off z hop? I've found z hop leads to stuff like this

This can happen with under extrusion or over extrusion. You can try the auto towers plugin on Cura and print some Retraction Towers.
