When buds burn and u get black ash that nutes people. Buds are stored at 58% humidity. Yall act like I'm a newb. Lmfao. Burnt leaves when only giving water means too much fertilizer salt in the medium which equals black ash and harsh burn. 10 weeks of straight water and plants still couldn't use up all the nutes stored in the medium. Jacks is too strong for me
Probably feeding at full strength and blaming the nutrients for burnt plants. Brilliant.

You are a newb if you're letting your medium get build up to that extent. So when does nature flush plants?

When there's no nutes in the medium then the plant will use up any excess stored nutes within itself. I wonder why ur plants go yellow when u flush, it's cause the plant is surviving on stored nutes in the leaves that are running out fast. It's from using jacks at 3.6,2.4, 1.2. Green genes even uses this recipe. So I guess he's a newb to. Just to hot fir my grow area

Saying you water only for 10 weeks and have burnt plants makes you look intelligent. Lol. Move along.
Everyone I know that's used 321 for the first time burnt their plants also. Ive never worked at the jacks factory so unlike you I didn't know. My humidity is 40%. I wasn't born knowing low humidity ment u must feed lighter. I'm sure u were born knowing this. I had to learn by trial and error.

I’ve been utilizing:
1/2 tsp a
1/4 tsp epsom
1/2 tsp calnit
Dissolved in that order and it has gotten me great results so far.
just started on jacks bloom and the plants are LOVING it.

But I thought you weren't a newb?

First time using Jack's I didn't burn my plants. I measure my EC...

Yikes, he asked for what ppl use to success, why the attitude and arrogance. Youre acting like less nitrogen and more pk in flower compared to veg isnt a well known beneficial thing and how dare he adjust jacks to be optimal for marijuanna instead of tomatos. You dont have to adjust pk levels for flower, but its been proven over and over and over again that you will get heavier flowers and more of them if the pk ratio is higher.

What i use to success is jacks 3-2-1ratio in veg to a ppm of 750-900ish, depending on which strain i am running. My chemdawg cut usually needs even higher ppm than that in veg.

In flower i also use monopotassium phosphate (mkp) and my ratio is:
2gram/gal jacks, 2.2grams/gal of calcium nitrate (calnit), 2grams/gal magnesium sulfate (epsom salts) and 1.6grams/gal of MKP.
Heavier feeding strains get that at 800 ish ppm and the lighter feeding indicas diluted down more in the 650-700 range.

Thats what i found gives my favorite strains the best results after having done 10+ different runs with clones from the same moms.

No "bro science" here, actual PPM readings and how they perform on the actual scale. Have you *actually* ran full strength jacks on rooted clones in a DWC or RDWC system? Because thats what his advice was for, not seedlings, and it works fantastically.
Clones are not seedlings they are cuts from an established plant and thus behave differently when the roots themselves are in an aerated nutrient bath compared to an actual seedling.

Its funny how shitty advice can be when you dont follow the *actual* advice.
Do you have a nicely laid out feed chart for the plant in veg and then in flower?

What is y'alls experience with needing extra calcium when using Jack's in Coco? Especially in veg? I feel like I overthink this, and often feed more CA than necessary, but I have had lots of problems in veg while trying to dial in Jack's 321. Does anyone actually thrive using the 321 ratio in Coco and using ro without extra cal? And to a lesser degree mg? I've struggled to dial in my veg mix. When I have tried 321 I had noticably better results after adding some calimagic lately, but seems a little rudundent. What ec are most people using during veg? I'm trying a little lower rh, accompanied by a lower ec. So right now I'm feeding at 1.4ec and just under 60 rh. I used to let humidity go up near 70 and I think it was causing some issues by not allowing enough transpiration
