You are right pH will rise with time as plants remove nutrients
Rubberbubbler Reviewed by Rubberbubbler on . Quick PH question...but no probs YET Hello everyone. Just a quick reference question: What does a lower PH runoff indicate?? My PH in is around 5.7-5.8. Just recently my runoff came down to around 5.4. There are no signs of problems yet, but I test the runoff every watering and it's slowly coming down. Just a few weeks ago it was coming out 5.9-6.0 fyi. The method chosen: coco perlite mix (botanicare readygro moisture formula), progrow, calmag, liquid karma, and an occasional small dose of peroxide. Am in week six Rating: 5
