Ch33cHanswered grow question 4 years ago Nothing, Stop over feeding your plants. This hobby needs patience and the more you leave your plants alone the better they will be for it. Not trying to be critical but you have alot of questions and problems and it seems like you are overthinking and overdoing your garden.
Flush is the go to when you burn your grow, Maybe a feed or 2 of plain water before returning to a less hot nute mix.
Good luck
