Omg I'm running low on my gen hydro PH down. I have some PH down for aquariums that is sulphuric acid 9.6 percent. Can I use this for my flush? Or should I push my girls till I can get my order in?
Good question and current topic, and that is, Is ph critical for a flush? You'll find plenty who don't bother, and I'm about in that camp. I would like to get a scientific answer. My thinking is if the idea of a flush is to flush the roots, why ph it down to a level which activates the nutes? However, I'm still in the better safe than sorry camp until my inconvenience threshold is exceeded ph'ing down water. How far off are you?
