Oh ya and here’s my 11 hour day in 1 out of 4 10 k rooms In coco I manage now for the old 9-5.
Growers sometimes make me want to say fuck it stop reaching out for help and stop giving any insight myself.
trial and erroris a farmers best friend anyway

How exactly did you determine the soil pH is 7.3?

It was run off..... slurry would be better?

Either way if I’m going in at 6.3 and coming out 7.3 I know my soil is having an alkaline effect on my water to say the least.
My opinion

A slurry will give a far more accurate representation of the pH of the media, but you are correct.
I'm imagining this mix being heavily amended with soluble lime, and it's being washed out.

I may not be locked up... my soil may not be 7.3.......... plants look great tonight I am dropping my water ph moving forward and will try to get that run off more acceptable.
250 ppm went in 1400 came out so still good bit of food in there I can watch that come down and I should be good to go.
Thank god for run off

Don't read too much into the pH of runoff, it is extremely misleading in heavily amended soil.
I agree although as a complete hydro grower my input isn't important. But my understanding was the microherd took care of the pH in soil. I get partial buffer in coco/perlite. I just don't bother with run off measurements pH or TDS.

I mean I haven’t seen this Trend often and I’ve run ALOT of name brand cannabis specific soil as well as have built my own.

Could you dive into that as little more ?

Microherd from my experience will allow you to float outside of range but nothing crazy as far as very acid or very alkaline. There are limits.

I wouldn't pay too much to the runoff EC either. That soil is amended and you're washing those amendments out and concentrating them in the runoff. You could take that soil straight from the bag and run distilled water through it and get the same runoff EC reading.

From clone they went into
1 gallon roots organic original with mykos watered with ewc compost tea.
They spent 5 weeks in there one gals under 96 watt t5s where they received protech silica some superthrive here and there as well as some aloe Vera and coconut water all light dilutions
Ro from the jump.
Week 5-6 they went into 5 gallons and same same compost tea while carrying along camg as of recently when I started to see issues.
they have been in the 5 gals for 18 days.
maybe “ I fed these plants” was the wrong choice of words.
There's always an asymptote in the mix or it wouldn't be exciting. I'll stick with Coco.

I have not done a slurry test and I agree it would be more accurate.Soil runoff pH is not representative of the pH at the roots. Chasing it can make things worse. What version of Coast of Maine are you using? If it's the Stonington Blend you shouldn't be having any deficiencies with plants. The thing with organic living soil is that you can't just flush stuff out and change pH like you can with say coco. You can flush all you want trying to lower your pH but a week later the runoff could be right back to where it is today.
Why are you feeding plants that small in an organic soil? If this is the soil you're using there was no need to feed them anything yet. Instead of flushing why not just water as normal with pH'd water? I think you're too focused on the runoff pH which is not a reliable way to measure pH. Have you done a slurry test? That will give you the actual pH of the soil.
If you're using this soil there was no need for any additional fertilization.

Organic super soil mixed for premium indoor container plants; includes ingredients like lobster/crab meal & mycorrhizae to promote budding & blooming.coastofmaine.com
These plants have recieved “low impact “ food man I’m talking aloe Vera coconut water at proper dilutions b vitamins and beneficial
Maybe food was the wrong choice of words.

Here's what I know. If I measure the "runoff" pH, I get a number nowhere remotely close, to the reading from a Blulab soil pH probe, in organic soil mixes.
