You should consider a magnetic stirrer then.
3 days on jack's 5-12-26 and the plants are loving it! Bye bye General Hydroponics forever

Interesting. Lol. I'm open to all kinds of tech.
I do like the concentrate idea. I think I might use that one.
The best gadget I made was my dry ice kief separator. It wasn't my original idea though. A guy on YouTube used a paint can hooked to a reciprocating saw with a bubble bag screen. I swapped the can for a stainless steel model instead. I works real good. The guy had a great idea. I give him credit. It's mainly for folks like me who can't physically shake a bubble bag for long.

two parts. I'm not good at video. Sorry.
Yes but how many mils per gal to get desired feed of the 321 nutrition

I have a 15gal rez, I use about 500ml each which gets me to ~1.4-1.6 EC. Comes out to 33ml per gallon. You may need to adjust the amount depending on your situation.
I actually haven't been being super accurate with my measuring lately and the plants are growing just fine. I don't even check or adjust ph anymore which is pretty nice.

It would be so cool to have a giant magnetic stirrer i could put a 5 gal bucket on and just toss nutes in!

One minute in a blender make the process way less tedious. They are dirt cheap! Cheers!

That would be cool. My old aquarium filtration unit had a magnetic pump.

I made a kiefer out of a little desk set of organizer trays. It has its own frame. I used trains arm/wheel mechanics as my inspiration for the mechanical parts to move the trays and used a 9v adapter with switch to power it on/off. It works great but it needs to be bolted down or it will shake itself right off of whatever surface it is on.

I'd love to see a picture! I looked all over the net for ideas. I considered a stationary model too. I got one of those small washing machines too. I hardly got anything for the level of work.
I love it!

Might not what you are asking,this is how I use jacks 321
I use a scale measure in grams 3.6 Jack's 2.4 cal-nit 1.2 Epson. Per gal I use 5 gal water bottles so multiply x5 18 gram jack 12 grams cal- not 6 sometime 5.5 epson
I used to use grinders, blenders ect. Now just keep each separated in jars ( cleaned pickle ,salsa ,tomatoes sauce glass jars)with water a couple days earlier so they fully resolved.

Hey guys, I have three plants sharing a reservoir of Jacks+calcinit and all three are showing showing signs of stress. I've been using Jack's hydro for a couple years and never had problems like this. All three plants are sharing the same reservoir so I'm guessing it has something to do with the nutrient solution.

Last week I had discovered the pH had shot up to about 6.8 and I brought the pH back down to 5.8 and it is currently at 6.0. The nutrient solution consists of 600ppm of Jack's 5-12-26 and CalciNit (Jack's 2-part). The RO water was around 10 ppm by itself. I usually get lush green growth from start to finish and this is my first time experiencing deficiency in the past couple years using Jack's hydro. If I had to guess I would guess either nitrogen or magnesium deficiency but I'm really not sure. I see some people online suggesting to run Jack's 3-2-1 if using RO water but I never have because I was told that the calcium and mg levels in Jack's hydro was more than enough and I never had a problem before. I am now wondering if I should be doing 3-2-1 formula with my new RO filter? Also wondering if it could simply be an overall nutrient deficiency due to having high pH before? But I corrected the pH a week ago so I'm skeptic it could be some type of pH lockout. The only other factors I can think of are lighting is too intense, or I'm overfeeding, or a combination of both maybe? Lighting is COB LED currently at 500 umol. The roots look pretty white and healthy and smell fine so I have no reason to suspect rot. The plant in the photo below is the worst of all three plants showing deficiency.
The other two plants are not curling down like this plant is. Which kind of looks like over watering? I'm using perlite medium that incorporates SIPS (bottom feed) concept and I've never had over watering symptoms before using this style of grow though.
Would anyone be able to provide some insight as to what could possibly be happening here? Would appreciate it if so as I'm not experienced with deficiencies and feel like I'm chasing my tail trying to figure this out! Thanks for your time and have a great one.
The strain of all three plants is Soul Mate by breeder Bodhi, and are three different phenos grown from seed. The plant in the bottom photo can be seen in the lower left corner of the top photo. Thanks in advance!

jacks+cal/nit+epsom you left out the 1 in jacks 321

Every Jacks feed schedule includes epsom salts, not just the 321. Start using it, your plants are begging for it.

So I should just start adding epsom salt to all my Jack's mixes even though I didn't have problems without epsom salt in the past? Not like it won't hurt to add, correct? Going to mix up a res now

What did you change recently than you did in the past? You mentioned a new RO filter. Did you run RO in the past? Different strain? Different lights? Narrow down the issues to what is different.
Yes I'd follow the recommended 3-2-1 schedule and keep an eye on your pH.

It wont hurt. I use tap water with 321 and still use epsom.

the leaves look like a Mg defic to me. i think that's why we all say add Epsom. i'd foliar with epsom maybe twice in the next day and that will fix it quicker

I got a new RO Filter a year ago. I just realized recently that it might be the reason I have been seeing my pH drift up so high. With my old RO filter I would mix up my Jack's mix and it would come out to 5.8 on the dot every time. My RO water was 50 ppm so I thought it would be beneficial if I get a new RO filter. My new RO filter gives me 10 ppm water. When I mix jack's with my RO water now I get a low pH and have to use pH up to bring pH to 5.8
I use potassium silicate to bring pH up since adding silica is beneficial to the plant. I have heard potassium silicate will drift up a lot more than other pH up solutions though although I have been able to keep pH stable with silica in the past. Not so sure if I can with my new RO filter. Also wondering if the lower ppm RO water I'm getting now is lacking in magnesium compared to my old 50ppm RO water which is why I may be seeing deficiencies now?
