What kind of water have you been using througout your grow?
I feel RO or distilled water is best for flushing. However, depending on where you live, your tap water may not be terrible. Have you tested it for pH at least?
...imo, flushing is hardly needed when growing in soil.
...when I grow in soil, I simply leach the last 3 weeks by only adding tap water and molessas only.
...in hydro, I flush for the last 2 weeks using sweet....all works great for me.
You've gone this far into your grow on distilled water, why change it up now? Save a few dollars at the very end and risk your whole crop tasting different than it would if you would've just done what you knew you shoulda done?? (run on, yes...)
I'll add this... if you want to use tap (whatever your reasons might be), make sure you let it sit for a day or so to let the chlorine evaporate out of it. I'd also check it's pH and ppm.... but that's just me.
