Flushing won't make a difference unless its from buildup, or your soil has something degrading at a high ph level and you manage to flush it completely. You need to PH your water and make sure its not the problem in the first place. Beyond that anything acidic. Coffee grounds, apple juice, etc, and dolomite lime to balance
hey, i'm having the same problem with my outdoors. the thing is, flushing didn't do the trick (it went a bit lower, like 7.4 and now it's back to over 7.5). they are 4 weeks into flowering and quite rootbound so i can't really make adjustments to the soil itself other than water. anyone has an idea?
also - i have a bucket of water standing outside to get the chlorine out of the water. so i lowered the ph in it to about 5 (to try and balance the alkalinity), but like a day after the water itself is back to ph 7. stirring it up a bit lowers the ph but not back to what it used to be. i'm using powder as a ph-down. bought form hydro shop . any ideas? appreciate it.
well i test my water its around 6 so im gonna try to flush with water,and my soil is good organic stuff,so i know its not the soil,unless the jackass at the hydro store didnt know shit bout growing?! and im new at this,so i dont know the diff yet?

Dude, I have the same "problem". And I use the quotes because my pH is 7.something, near 8, but the plants look pretty good. I've tried to flush it (my tap water is 6.5) and sometimes adding some lemon but it stays quite the same. As they are doing good so far, I won't worry about that.
If they're doing alright, just keep checking your pH to make sure it isn't becoming more alcaline than that. If it doesn't, relax!
Cheers!
