I watered my Northern Lights with tap water PH was 6.7 PPM about 71. When i checked the run off the PH was above 8.2 i flushed it and got it down to a Ph of 7.66.Should i keep flushing it to get it below a Ph of 6.5, It is a 5 gal. fabric pot i ran about 10 gallons thru it.
What type of soil are you using? And yes keep flushing it but don’t do it all in one setting. Do 10 gal flush then wait till next feeding to flush again. I recommend using distilled water to flush because distilled love to take out nutrients. That’s my thought on it
Black and gold organic been using it for 3 grows and no problem. I have a Blue Berry in the tent same soil planted at the same time. Her Ph is 6.41 PPM 586. The NL PPM was 564.
