If it's not draining flushing wont help much. The bad gunk will still be there and the pot still wont drain.
Slevinkal Reviewed by Slevinkal on . My PH took off and I need to adjust radically Team, My PH is over 7 approaching 8 in my outdoor soil grow. Thanks to the hints here I was able to detect and now I know why some of my ladies are yellowing. I used some vinegar as directed yet the soil is still over 7 as measured with a low end probe meter. I used my pool chemical tester to determine my tap water is near 8.0 PH and verified with probe measurement so I know where the problem arose. Are there any long lasting PH soil adjuster you recommend other than vinegar similiar Rating: 5
