Dude I am simply eliminating variables to find a solution to my problem. The SOIL at or above 7.3 is a contributing factor and I have done nothing abnormal to get it there.

also I spoke with a rep to figure out how much coco coir was in the substrate and the quality to find out a bit moreabout COM cat ion. Potential variable for my mag and ca problems. While speaking with the rep I asked if they limed the soil he said they used to until they got feed back that there soil was running to alkaline.
Good information for me to gather.
I apologize if I came across as blaming the soil but at the end of the day it’s high ph could and probably is a contributing factor.

my feeds are organic inputs with low impact.
tbings like coconut water aloe ewc teas.

this is far from my first rodeo in soil
How bout some aloha vibes or some info pointing me in the right direction.
Which I may be two steps ahead already
Blessings
Aloha. They look pretty good.

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

Your other ideas were good too. EWC tea, and so on. Adding organic matter like compost will naturally lower the pH also. 1tsp/gal of Neptune's Harvest Fish and Seaweed will lower my water pH to around 6.7, or 1tsp/gal Earth Juice Grow brings it to around 6.5. Earth Juice Bloom brings it around 6.5 too.

I'm on my 5th grow in the same soil, and realized I have been amending with too much Ca. My water already has plenty Ca, so it's building up and causing my pH to rise. I have been doing a mix of feedings to slowly lower the soil pH. Citric acid one day, then Neptune's Harvest, Grow or Bloom the next, then plain water. Slowly my soil pH is getting back to where I want it. The citric acid is supposed to help flush out the extra Ca, and I believe it after checking the citric acid runoff. I'm trying to be able to just use water only and top dressing when needed, but am still learning no-till.

I think it was @kratos015 that I learned this from, but I am a stoner.

Ranting so hard I forgot what I came on here for it was to thank whoever gave me the Epsom tip I’m sure it was a few people but last night I foliar we epsom
First time I’ve ever done this.
Along with my last watering camg maxi crop super thrive and the Epsom foliar plants look like they had a very vigorous day today.... container driving quicker
I’m flipping soon. Stoked

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
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

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.
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.

How big are your pots, and have you had the plants in the same pots the entire 10 weeks?

Besides messing around with pH and flushings, what have you done to the plants or fed to the plants? Like have you been using any nutrients or anything?
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.

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.

I have not done a slurry test and I agree it would be more accurate.
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.
