Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄
Looks like over watering. Drooping leave usually indicates an over watering situation. Taco and clawing leave the turn brown a crispy at the end is underwatering. The yellow could be a nutrient deficiency. Lower older leave indicates it an immobile nutrients. Usually nitrogen.
