will plants out grow nutrient overdose

i gave my plant to much nutrient and now there sick .will they out grow nutrient overdose if i gave them straight water from now on .

flush your plant immediately with plain water

How long it takes and how well it works Depends on how bad it is now and how long ago it happened, flushing the soil will help for sure but the damage done isnt reversable so if its already really bad dont expect any miracles from her after flushing, it might take a long time to recover.
