To make a long story short i am experiencing nutrient lock up due to low ph i am currently running fresh water to flush her out. she has been in the fresh water for over 36 hours already but what i dont know is how long do i keep her in fresh water as opposed to changing to a really light nutrient solution and when is it ok to go back to full strength nutes.....i have heard u flush until u see signs of deficiencies but she is already experiencing deficiencies due to the nute lock up so HELP is greatly appreciated
