Couple of times I’ve noticed my runoff is 5.0 it goes in at 6.5 so I’m wondering why? What can I do about it? Is this normal? This is only my 2nd or third soil grow ever -thanks for the input

Your plant using what is in the mix changes the phone most of us check and correct multiple times a day

Why do you want to know your runoff pH? Simple- it’s an indication of how your water, fertilizer, and grow medium are interacting chemically. There are 3 measurements that are important to know when you are caring for plants growing in a soil or soilless medium. The first is the pH of your source …

[image] Paranorman: Is this normal? Yes and no. It is normal for the pH coming out the bottom to be a little lower than what is going in. If it was going in at 6.5 and coming out at 6.0 – I 'd say you have nothing to worry about. In most soils with a lot of “organic” and composted material,…

PPM is exactly 600 + 95 from the tap (695 total), my tapwater is 7.1 out the tap I’m taking clones and starting the switch tomorrow on some of the plants in question I’ll probably flush, but I would still like to understand what’s up, that seems a bit low to me Everything looks good growing norm…

Tap at less than 100PPM and pH at 7.1, you probably don’t need to be downing the pH at watering if the pH coming out is so low. ~MacG

I agree @MacGyverStoner correct me if I’m wrong, but I think some where through drainage there is still an acidic patch in the soil causing it to go in fine and come out acidic, maybe try to touch and reset every thing @Paranorman

I’m going to do a flush and I’ll check the runoff after, I’ve only noticed it in two plants so far -thanks
