"Runoff pH is useless" or "Keep an open mind"?

Just fed mine. I don't usually take pics, but here's a few. None of these have been topped or anything.

Veg tent with 5000k.

Flower closet with 3500 and 3000k HLG. This has been in here since it was little. The structure is different with the lower Kelvin spectrum. She's a little limpy because she just got fed and watered.

Holy fuck the ever vegging plants. I’ve harvested twice since you put these in this tent.

but again how do you know what’s happening within the rhizosphere as far as pH is concerned when testing runoff pH in mediums that buffer?

see what I’m saying?

As a test I’m going to check my runoff pH later once im home from throwing the arrows just to see what it’s coming out at because I know my plant isn’t struggling for anything and that im
Feeding at 6pH EC 1.2.

The runoff EC is between 0.8-1.0 which I know already.

I would expect my runoff pH to be around the 6.5-7 due to less salinity in my runoff.

but we’ll see later.

pics of the plant in question that I will be testing. (Sorry @bk78 for posting another pic :p )

Forgot to say 2Gallon pot 100% coco fed every 3 hours.
Ok here we go for those that want to know or even care.

EC in 1.2
EC out 1.0
pH in 6.0
pH out see pic and judge yourself

I'm not certain of the coloring, but it seems like runoff is somewhere around 7.0 to 7.5 pH. Were your system mine (I'm not telling you what to do), I'd want to know what happened if I adjusted nitrate:ammonium so that pH out was around 6.0 (which was your pH in).

Bro Science crap - have never tested in soil or coco, waste of time, better things to do - smoke good buds , dont worry about shit you cant fix, if you can fix dont worry smoke more
So you've never tested pH, and don't think you can fix it if it's off? Please tell me more, lol.

dont care what comes out - what goes in is the issue , only time I check PH or EC( TDS) is on the farm with the crops when liquid feeding hydroponic DWC only)..
Cannabis- never said you cant fix PH- I always check/adjust ph 5.8-6.2 going in and adjust up with silica only ,never out using soil or coco no point -
