I just recently switched to hydro, ebb and flow and have a question about ph levels. If i have a barrel of feed and water with a ph of 6.5, can I just add "ph down" to bring the ph down to 5.5 or should I just drain the barrel and start over? I just wanted to make sure because i was told to adjust ph before adding feed.

Thank you

Josh
