I’m using filtered, ph adjusted 6.0 water to raise runoff. One gallon into flush (I’m pouring in one small cup at a time) ph meter now reads 5.0. Could the ph down be the culprit or am I jus getting an idea of what the center of the container really is. I have heard of putting a much higher ph in to compensate quicker but I want the top to be around 6 as well. This whole flushing thing is new to me. @pigSquishy, @Paranorman, @latewood I would ask more people but I can’t think of their names. 🙂 ---

you have the right idea this is why I say flush slowly lets water saturate and what comes out is far closer to what’s at root zone I would raise ph of water 6.3-6.5 check result after you are definitely on the right track ---

rjw 71\_ Well if your adding ph down to your 6 .0 water then. Your answer I yes . Stop adding pH downkust flush with the 6.0 wastet William ---

Water is 6.0 after adjusting. Sorry I could have worded that better. ---

Yes, I want to put a little higher ph to it so maybe this won’t take so long but will ph on the top still end up around 6.0 ? ---

Well 1 1/2 gallons later and I’m getting a 5.1 reading. ---

how large is pot? and plant in what stage is she at ? and yes using water with higher ph will raise ph but lets see if we can find any other reasons it may be so low ---

I would pH it at 6.8 or even 7.0, then once I got what I wanted I would run my last gallon through at about 6.5, give or take I also like to raise or turn down my lights or put plant to the side for a day or two after flush -good luck ---

I just want you to rule out underlying issues that may be causing the drop no sense flushing if you need a transplant would just create extra stress best done all at one time ---

not arguing the method just don’t have all the info yet to make sure it’s treating not increasing problem 😉 ---

I pre mix three cat litter containers ( four gallons each) and let them bubble over night. Well, three gallons through the first bucket I realized I had forgotten to adjust ph. As I panicked I stuck the ph meter in and it said 4.7. That’s what I get for burning one while waiting for the lights to come on. So I used three gallons of just filtered water (ph of 8) then I continued with mix at ph of 6.1 until I started getting runoff. Then I extracted the runoff. I did get a reading of 5.4 then but I thought it was because of the dirty drip pan’s influence. ---

Reading what you said originally; I also recommend you mixing your water at 6.5-7.0 in order to balance you PH. One note. If you are adding properly PH’d water and the plant is doing well; Don’t worry about it. If you are having issues due to the PH being off, it is best to try and balance the PH. 🙂 ---

That makes sense, thank you. Running all this water through is bringing my temp down. ---

Hey Paranorman. Will my plant suffer if her roots get down to 60 degrees or lower ? ---

This would mean I could use less chemicals and water to balance things out without flushing all of the ecology I’ve got going on. Thanks again. ---

Thanks pigSquishy, I have finished with plant #1 of six. First one had 64 degree runoff. I hope that’s not too bad. ---

Hey there @garrigan62. I put 8 gals through each seven gallon pot. Now that the runoff is 5.8 will she pick up potassium that is still in the medium ? Or should I not wait for medium to dry and add nutes now. [Next page](https://ilgmforum.com/t/growing-in-promix-runoff-is-5-2/6118.md?page=2)
