6 is fine, but make sure you are tesing PH after you add the nutes to the water. Use Advanced Nutrients until you get used to it, because they don't need you to PH everything.
Should i harvest now before it's too late?

That's low for soil. Low pH can lockout K too.

I would check ph of run off. First thing to address in root zone always ph because if that is off nothing can work correctly.
th ph you are putting in is not the same as the medium.
also runoff ec. nutes can build up in medium messing up medium ph and ec

6.3 to 7 recommended PH to avoid K lockout for soil media, but I wondered if he was PH'ing the water before the feed

Just water or water and ph down??

I tested a few times. Water started out at 6, "Pre-Feed" and with the nutes was right around 7 or just below.

Just water. PH around 6 to 6.5.

That could be your problem then, you need a 3rd reading from your run-off. That's always your final test for the sweet spot

does using synthetic or organic nutes change optimum ph for soil?
I went 6.3 ph for organic and great results so far, couldn’t imagine salt nutes would want much higher.

FYI your soil is the environment the roots are in and your canopy can only get as big as your root system will support, so the PH of your media is what you want in the right range for uptake of N-P-K, copper, magnesium, iron, etc. If your media runoff is steady between 6.3-6.7 throughout then you're gonna be on the right track.

I don't believe organic nutes buid up much. I haven't run them yet, i've wanted to for years just been chicken. Heard and seen really good things

I doubt it, because the PH only determines the uptake of each mineral for the plant, the media might keep a certain PH, like cocoa might be more acidic, but that environment is what you maintain for the uptake of nutes

I just mixed organic alfalfa pellets in organic bag soil and used peat to ph soil to 6.3 watering with 7 ph. Plants are loving it.
Alfalfa pellets 2-1-2 average. Alfalfa pellets basically free, soon just gonna use harvested weed plants to mix in medium, must be perfect nute

I mix my own, ocean forest, pearlite, cocoa choire, peat and spagnam, vermaculate, azos and mykos. My plants almost need fed twice a weeek, but they eat every drop and they're downing a gallon and a half each every feed with zero burn

almost opens another can of worms.
now I think it is best (a must), to make ph of medium ideal before starting grow, to help avoid headaches down the line. Also consider ph of water being used

to be honest, that was originally why i added cocoa knowing it would need more water, but i'm getting older and lazier and I went back from the fancy stuff back to AN nutes for simplicity. I screw up less often to the point it's just worth the (barely) less peak results. Especially considering everything I grow is personal. After a decade of PH UP/DOWN and harvests my hands almost crippled. It's hard enough for me to get it all trimmed

@ op, when run off ph and ppm/ec is good your plants will be good.

Is there a PPM I should be looking for, from the run off?

I hear that, got auto watering and just fill a res once a week or so. Haven’t had any plants full run on this yet but getting close and all seems well, never feeding.

1.3 ec/700ppm or less imo. Going in and coming out, may vary with your nutes, I think 2-1-2 always/only whole grow
