It looks like calcium deficiency, not nute burn.

@VILEPLUME. Can you provide some details?
Type of soil? Brand?
Nutrients used. Feeding frequency and strength.
Water source? Tap, well, mineral, distilled.
To me, just going off of what you have pictured, It looks like a couple things. First would be over fertilized. Second would be potassium deficiency.

Yea, some extra info would be good.
But I would second the calcium deficiency idea.
Calcium deficiency tends to leave brown spots like that, progress down the leaf and all the way to middle.
Potassium deficiency usually shows more on the leaf edges. At the very beginning it could look similar when just the leaf tip is getting discolored.
As for calcium deficiency, check what you are feeding, humidity levels and that you have enough air movement to have good transpiration.
Calcium is pulled passively within the plant, so you need to adjust transpiration to feeding levels.
Also consider that too much of K will interfere with absorption of Mg,Ca. Same goes the other way.
