Nutrient burn

My plants have experienced some minor nutrient burn. My question is; do I need to flush my plants no matter what? Will the nute burn continue to get worse until I flush them or will it get better? or do I just feed them regular water and wait? Thanks for any feedback.

Flush em, 3 times volume of pot...ei... 1 gal pot gets 3 gals water, they`ll love ya for it,
if ya don`t flush you stand a greater chance of salts build up later and you really don`t want that.
