Leaves twisting and dying on only 1 budsite

[MikeTahoe]

So its my first ever attempt at growing and I've done fine so far, using fox farms soil and liquid fertilizers for veg and now flowering, havent had any issues till now, yesterday I noticed some lower leaves shriveling and dying on a side branch/small budsite, I didnt think much of it as I heard cannabis does this to leaves not getting much light and it's natural, however this morning I checked and noticed all the leaves up top are starting to curl and twist as well, I'm not sure why because the rest of the plant is healthy and not a single leaf on the rest of the plant is showing any signs of problems so it's hard for me, especially as a beginner to diagnose it, I would really appreciate some help

Maybe she’s so potent she’s tripping balls on herself?

You could have a heat spot near that area. Leaf curling is usually a sign of high temperatures.

Is it possible to have a heat spot that isolated? I was thinking the same but the fact it was only on one side branch of one plant out of 3 I just wasnt sure

Have you checked for bugs?

Yea I've looked all around, even using the jewelers loupe to get a real close look and nothing, should I just prune the whole branch? Or is whatever happening not going to affect the whole plant?

It is. I'd make sure that you have air flowing in that general area especially when the lights are on.
