Not sure what this is...

Alright, I cant find anything that resembles this. Is this chlorosis? Maganese deficiency? WHAT.
I'm growing in organic soil, 6 weeks into flower, fed with bat guano top dressing, and molasses with every watering. This is appearing on almost all of the topmost leaves, and I can't for the life of me, figure out what it is.
I CAN tell you what it is not.
It IS NOT bugs, it is NOT a ph/lockout problem (come on, I see that kind of response in almost every thread), and I'm pretty sure it isn't overfeeding (who the hell is stupid enough to burn their plants with organics?)

Any help/advice would be greatly appreciated.

Well whatever deficiency it is I don't think it's anything to worry about at 6 weeks flower, ur gonna be flushing soon right? ur tips do look crispy tho...

No, I'm pretty sure with this being a sativa dom pheno and from every journal I've read on this strain, it's going to be a 10-12 week flowering time..

Won't worry about it this late in flower, give her a good flush and let her mellow. I would be sure to clean everything with some physan after the run just to be on the safe side.

I'm only like halfway there...

Nobody knows what this is?
