minor nute burn question

a few of my plants got burned on the tops on my smaller plants.

on the bigger ones some of the top buds turned brown prematurely.

im just wondering since i have like 1-2 months until i pull them if they will be able to recover from the burn.

If you think your nutrient burn would get worse then, I would flush the medium your using with 2-3 times the volume of your containers. That will not make your visible problems go away but it could prevent future ones from happening.
