Follow whatever advice appeals to you, but in the situation that I described, "flushing them" only made things worse... because the water doing the flushing had a ph that was too high.
Sudden problems? Water ph testing! Nutrient lockout? Advice needed :3

Our experiences have been different. Whatever works for you. I know what worked for me.

Oh ya, if your soil is tweaked to start with then you would need to PH it, or if there are high amounts of acidic or alkaline amendments in the soil, Most brand name soils are usually mixed at a decent ratio, so that they buffer pretty well and nothing is too acidic or alkaline. If you make your own you might add too much of something or to many different acidic amendments and tweak the soils buffer shield

I understand but her problem is not the same as yours and she has stated already 3 times that her soils run off is 6.0 which means she would have to runs 20 gallons through the soil to get it to be 7.6ph..... The soil is buffering her water there is no need to PH in her case....she runs water through and it comes out at 6.0 it is fine

For what it's worth... in Marijuana Grow Basics, Jorge Cervantes says this about ph: "Marijuana grows well hydroponically within a pH range of 5.5-6.5, with 6.0 being ideal for soil."
Also this "...Every full point change in pH signifies a tenfold increase or decrease in acidity or alkalinity. For example soil or water with a pH of 5 is ten times more acidic than water or soil with a pH of 6." TEN TIMES!!!!

Some soil mixtures are bad buffers, which is probably what happened in your case.
even so...that "TENFOLD" change is easily buffered by soil. As soon as the soil absorbs the water the ph either rises or drops depending on what is in the soil and what buffering agents they put in it. If you load soil with dolomite lime and run 9.0 ph water through it, it will come out at 7.0 because the lime reacts to it and neutralizes the water

Fortunately she provided the water analysis. The ionic strength of that water is not high enough to make the high pH an issue imo. cn

I am in no way saying you are wrong man. It is just easily seen in this case that flushing is the best option and her water source being 7.6 has nothing to do with her problem.
now if she had a bad soil and it wasn't buffering her water then yes your suggestion of not flushing because it would make it worse would be sound advice, but it is not in this case.

I was using a soil mixture with bat guano and all that good voodoo but no knowledge at all of the soil pH. I can't argue at all about making judgements based on the pH of the runoff... because I have no clue how the math works between water in and runoff out... how the soil pH can be determine by comparing the two readings I mean. I admit that. The hydro store dude once said that to really get accurate pH readings of the soil one would need to use an expensive meter like a a Bluelab $300 soil probe equipped meter... byt if you could share how to do the calculation (how did you compute the 20 gallons required to affect that level of change) that would be awesome. I'd appreciate it and throw some rep your way!

Thank you, I won't give advice about something I am clueless about, like that water report, I left that ball in your court. I have a lot of spare time and do a lot of reading.No worries; I got yer back. (And by that smilie, it looks like you got mine. A little to the left ...)

you should not be flushing with 7.6 phed water, you should ALWAYS make sure your p,h is between 6.2 and 6.8, I would flush with water in that range and forget all about the damn runoff, it means nothing.
you people over complicate things, it's a weed, keep it simple and quit turning this into something hard.

Sticking a PH pen into runoff water is not hard....Or is it hard for you??
