Sweet Tooth Auto - Weird behavior by one of the buds

Can anyone tell me what this is? Never seen it before.

Just bumping. Is it nute burn?

No nute burn would start at the tips. Have you scoped for bugs? Can't say as I'm familiar with your particular issue but definitely not nute burn.

I have some leaf miners (A couple) and slight signs of thrips, etc but nothing critical. But I've never seen this before. All my other plants are fine by the way, it's only this one showing this particular symptom.

Not sure, but it could be russet mites..

I might be wrong, but I don't think we have those here. I don't think the damage looks consistent with the pictures I find of Russet mite damage either. I haven't seen a single bug on the plant either. I appreciate the suggestion tho, I will check it again when the sun is out and see if there's anything I missed!
