Only plant with this problem

Haha catchy title...👽
I was wondering what y'all think might b wrong with this grl I believe it to be potassium def. none of the other girls seem to be showing any signs like this so therefore I'm ruling out light burns and any other type of def. I appreciate everyone's advice and time in advance

I seen your other question so maybe a ph problem?

It looks like classic nutrient burn to me. Are your plants all the same strain? Different strains often need different nutrient levels.

I'm with Dagmar looks like nute burn to me, I see it on the background plants too. I'd flush them all and see how they respond, maybe be try 1/2 nutes on the first feed after flush.

Nute burn or light burn eather way look a little cooked to me .02$

I agree, the brown curled leaf tips are signs of neut burn.

Could be a bit of nute burn or calcium/magnesium deficiency.
