Ok guys I just realized my Hannah pH pen has been giving me the wrong pH, and so I have been feeding my plant with much too acidic solution for god knows how long.
I realized this because I tested my pH pen into a gallon of distilled water I just purchased, and the pen read 4.5 pH... If I understand correctly, distilled water is 7.0 pH. Should I calibrate my pen according to this? I ordered some 7.01 buffer solution but it's going to take a while to get here..
Also what should I do with my plants? Do I need to flush them ? Or just start feeding them with properly adjusted pH?
fuuuck this could be bad, one of my plants is lookin pretty ugly. 15 days until harvest too...
