I’ll let you know what I hear for sure just so we can all know what they have in it. I will be watering tomorrow morning. I’m going to give it calmag with some nutes ph’d at 6. My next grow I may try that coco peat too.

If you are doing living soil you are fine and within range. The microbes you are nurturing have the ability to actively transport the nutrients to the plants despite being out of the nutrients soluble range in water. The problem when the ph goes up those nutrients become locked up to a salt. As the ph goes down to ideal range those nutrients become “dissolved” and free; not bonded up tight to a salt. So your plants can slurp them up in the roots.
Living soil like yours you will have no problem at 7ish range on run off. I would say trying to fix this problem will just cause you problems later with stripped out nutrients (like @PurpNGold74 said) or worse throwing off your microbes. Outdoor you mentioned the higher ph was not a problem. The outdoor soil is a loaded with microbes to feed the plants. The microbes make all the magic happen in living soil. It is the most common way “locked” nutrients are let free in the soil for plants.
I think you are just fine. Assuming you are using that soil as living soil. And not rocking the salts bottle feeding.
Edit: one more vote for some epsomsalt.

Wasn’t quite as informative as I was hoping, but basically they’re saying the same thing a few of us said. Runoff doesn’t give you an accurate soil pH number.
Are you using salt based nutrients, or do you have added dry amendments in your soil?
One of the most informative things I’ve read about pH over the years is Big Mike’s pH Manifesto. It’s easy to find online. A long read, but well worth it if you want a better understanding of pH for cannabis growing.

I’m using the fox farm trio and cal mag. I’m going with the answer I’ve received most- worry about the ph of what I’m putting in and not to chase runoff ph unless I see a problem. I fed some nutes and a good dose of calmag and I think she looks pretty good.
I’ll look into that manifesto though. I never turn down information. I also agree the email they sent wasn’t a very thorough answer on their part.
