What is the ppm of your runoff?

I have always nuted and watered alternately in a product like that. If your plant is using lots of water but not using the ferts as fast, it'll "concentrate" the ferts right in the pot. Acidic ferts get to be stronger acids, at least all the ones I've ever used did...
DreadedHermie Reviewed by DreadedHermie 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
