Any ideas why this is happening

Hey everyone couple plants are doing this don’t know what’s happening
Is it a possible nute burn or something else ?
growing in coco
Week 1 of flower
1000ppm feedings

Cut back on the nutes.

The chattered margins would suggest a Potassium issue, but you're also feeding a good amount...which would make me look at my pH. Good luck.
