I've always read hydro you want more acidic for the chelated nutrients and in soil more base.

5.5-5.8 in hydro like dwc etc.. but I do this for coco too.
Then 6.2-6.8 range for soil.

But if you had success in coco in 6.2 range then I can't argue with results. I just usually go a little lower.

There's so many factors to take into account with all the various methods and systems people are using in hydro I generally let other people answer even if I have some insight.

Regardless of medium I think that nutrient availability vs ph, the sweet zone is 6.2-6.8 like you said for soil. There's ph swing to account for outside of soil because of the plant using whatever it thinks it needs vs what you're trying to cram down it's proverbial gullet.

I didn't have an issue with my plants while not phing a whole run using 6/9 with foxfarm powered boosters and 250ppm tap in coco. I'm sure the ph ranged from 5.5-6.5 and my plants didn't give a single fuck.

Maybe we're over complicating this lol.

Maybe you guys can help me out with this OBS #3. This plant has these spots forming on lower leaves (my CC had this too). I added 3 ml of calmag per gallon to try to combat this when it happened on my CC and maybe (?) it helped. This OBS started it while in veg and it isn't getting any better. This plant is growing in 100% perlite, getting Jacks 3-2-1 (3.6 grams-2.4 grams-1.2 grams) and 3 ml/gallon of calmag. Ph'd to 5.8-6.2, fed nutrients every watering. Please help!

I've run hempys for a while and have experienced this on some strains when running pure perlite hempys. It MAY be a ph issue due to the perlites low cec. It's the reason some plants in your garden(if all hempys) will do it and some won't. Let the hempys ph drift in range when you ph your nutes...I mean, don't try to be exact and readjust trying to do so. Cal/mag Is like a bandaid for the issue, it's either Cal OR Mag.
I've since added calcinined clay(turf builder or kitty litter) to my hempys(solo and 1 gals mainly) to alleviate the issue.
I had a pineapple express that did this no matter what, until I lernt about perlites cec ability.
Pure perlite hempys run like a well oiled machine....until they don't. Vermaculite was Hempy's solution.

Some good info here.

Also, pontificated a bit and thought about the order you're adding your nutes together might change the pH over time after you stick your sensor in it. Silly idea but worth an experiment.

Could be a thing as well. Jacks has a certain way to be added after it's been mixed with H20. Been a while since I've used it. Only reason I don't now is because the brick and mortor no longer carries it, and my megacrop sample was there to try just in time.
I really like Jack's cleanliness compared to mega. Both perform/ed for me splendidly.

Oh yea, perlite based hempys I ran my ph@ 5.8-6.2< Coco based with perlite mixed in I ran them @5.9-6.4< In hempys the plants will tell you rather quickly if their roots aren't happy with the ph, a day, two max. Chasing exact ph causes more issues. Another misnomer, the hempy res doesn't always have to be saturated. It's ok to be dry by the time it's time for the next watering/feed.That is, IF your media has good capillary rise and water retention. Now, in my solo cup hempys with the calcinined clay and perlite 50/50 mix, 5.9-6.2.

symptoms are a mag deficiency. i would use epsom salts versus supplements for this one. almost cant overdo it with epsom in soil, but being hydro I would probably do teaspoon a gallon.

flush , foliar with epsom if you wish. mag usually gets locked out with low ph, versus high. i would shoot fpor 6.0-6.2 ph in perlite.

Unless your soil ec gets to high then you can deffo fry some shit with too much epsom in a soil grow.

I am already using 1.2 grams/gallon of epsom in the Jacks 321. I agree the cal mag is a bandaid, but not sure what is causing this issue. To compound the problem, I have 12 different plants of several different strains in various stages of veg and flower all using the same nutrient reservoir. I am trying (unsuccessfully) to use a single nutrient formula for all of the plants, which is why I am using the Jacks setup.

Also, the Jack's I am using is their hydro professional 5-12-26 IIRC.

Vermiculite with perlite, or straight vermiculite?

Jack's 3-2-1- can be an all in one nute ( technically 2 parts..but yea) It was for me. I ran two tents off of one res with it. If the affected plant is the only outlier with the issues, by process of elimination... that bucket has ph issues and not a deficiency could also be a lockout of some sort which goes back to ph. Megacrop is a damn good true all in one nute. They have free samples too.
Maxibloom also worked splendidly in my hempys.. for another all in one nute.

Maxibloom always landed with perfect ph when I've used it in the past too btw with no other additives or ph adjustments

There are a lot of factors to consider, or ignore, for sure. The base nutes I use, from the folks who make Jack’s, is called “Oasis Hydro FeED 16-4-17,” (which are the NPK numbers,) says on the bag it is effective to pH 8.0. I know iron dtpa can be absorbed up to pH 7.0. I ran coco between 6.5 and 7.0 for years. I run DWC hydro between 6.0 and 7.0, anywhere in there is fine. I will let it start as low as 5.5 sometimes, though, zero fucks given. One thing you learn in the aquarium hobby pretty fast is pH is not likely to be your problem unless it is way out of range, and that some amount pH swing is a good thing. I brought those assumptions with me to this game and haven’t seen any apparent ill effects. Most of us sweat the pH thing way too much, in my opinion.
