yeah i always used to flush myself and im kinda starting to lean towards the idea now that flushing has more negative effects than positive, loads of people tell me that all you do is deprive your plant of nutrients at the time where it needs it most, right at the end, to produce all those terpenes, trichomes and swelling up. and starting to think only time i do need to flush is if plant is showing signs of any toxicity/overfeeding
loads of people will tell you different things, but best way to do it is try all the methods, and see what you think yourself.
