So I am using FF trio and there has been a bit of a buzz about using sledgehammer. I haven’t been feeding them a lot of the trio but my ppm is reading around 1800 when I did my last pH watering runoff. So I say to myself that they don’t need any more nutrients because the ppm is high. Would I be safe to assume this? So I know the sledgehammer is for flushing and breaking up the salts. So can you just use sledgehammer as a regular watering or does it have to be a flush? All my girls are doing great so not wanting to fix what is not broken. @bob31 @Countryboyjvd1971 and anyone else that has experience with them. comments welcome.
