Hey guys, nute burn or deficiency?

Hey guys,

Im new here and this is my first post- while ive scanned the forums for pictures and answers to this, I figured it best just to leave up a picture and tell me what you guys think. I'm about 7-8 weeks into an outdoor grow, and the strain that is experiecning problems in particular is an autoflower. I think the problem is nute burn for the leaves that are dying from the tip in, but one leaf has some spotted orange/yellow, which might be more consistent of a certain deficiency of PH imbalance? Let me know what you guys think, thanks in advance- SWIM

that's an unusual presentation

im not sure

First guess, it's animal piss. ammonia burn
..but it is kind of localized to that big leaf looking more like internal plant issue..

I dunno...

Those pics are of 3 seperate leaves actually, if that matters. Animal urine im not sure cuz those leaves must be 3 ft high or so from the ground, what animal pisses up there lol? Ive been feedig them the floragro series of nutes per their schedule

Oh you would be surprised, I've seen little kitty spray 6ft up the wall..
it's all about where the butt missle launcher is pointing. lol
Just sayin...

(Sorry I can't help you really, I just don't know what I'm looking at in the pics.)

The leaves do look pretty super dark, I wouldn't feed any fertilizers anymore for a while, until the super dark green fades out a bit to a lighter green telling you they are hungry, just fresh clean water for now in my opinion.
