There's some good bits in here about trace elements.

Jacks (JR Peters) nutrients

Tell me this aint dumb luck? Not wanting to go through the hassle of ordering nutes from jacksnutrients because their packing tape advertises "Jack's Hydroponic Nutrients", I decided to get Peter's Pro 5-11-26 from Custom Hydro because they ship discretely. The tradeoff is that Peter's Pro has a bit less P and Epsom than Jack's 5-12-26. So I plugged Peter's Pro and STEM into hydro buddy, and low and behold the micro levels are about spot on to my targets, much more so than I was able to achieve using Flora Micro with Jack's, and if memory serves me, also STEM with Jack's, though that doesn't seem right as Jack's and Peter's have identical trace element values.
Edit - I still have all of my other products meshed in with the above numbers to achieve all of the other targets. I was just so excited that the micros hit nxsov's targets that he shared, so I won't need to supplement any of the micro levels to get ideal results.

It looks like they have a wide variety of formulas, but I can't find any links on their page to individual products unless they use the same blanket trace element ratios for all of the formulas. I never heard of this brand though so I'll be looking for what I can about them regardless.

They got a 5-11-26 too. I wonder if it's a repackaged product?
yeah I visited a friend up in norcal and he took me to one of his friends grow (light dep) and when we passes by his mixing area i noticed the product but didnt ask about it at the time. i never heard of them either but do know that hes been growing for 20 or 30 years which got me wondering about it.
another question but about Jack's. I use the hydro + calnit bought on ebay or Amazon. everyone shows pictures of the blue color bag with Jr Peter's product # 77251 but I always receive a bag that's a light blue with jr Peter's # 79030. both have the same npk printed on the bag. on jr Peter's website they show the Jack's pro hydro # as 77251. I cant find anything about the 79030. anyone have any info? thx in advance

nm I figured it out. one is Jack's hydro and the other is Jack's pro hydro. for people ordering from ebay or Amazon double check that you're getting the correct product 77251 if that's what they are advertising. some sellers will send 79030.
a quick glance and the 79030 isnt listing any so4 in elemental ppm.

I have a question if you dont mind helping me out. I recently changed my ro membranes and my water comes out at 0ppm. I do top feed drain to waste with rockwool Hugo's under 1k gavitas and 315w cmh between. i use Jack's hydro 5-12-26 calnit, mpk and Epsom.
for bloom I've been using
2 jacks
2 calnit
.75 mpk
.75 Epsom
after mixing my ph is around 4.2ish.
I then add about 4-5cap fulls of advanced nutrients ph (0-0-45) up to get my ph to 5.8-6.0. about 220g resi.
I remember you saying that a lot of K can mess things up and I was concerned if I was throwing things out of ratio. I wouldn't mind using silica to ph up but I dont know it will affect the ratios.
I've also been intrested in trying jacks aqua gold finisher 7-15-30 during bloom and was curious on those mixing ratios.

K2O and SiO2 in the AgSil values reduce to
K - 26.5632
Si - 24.7315
K - 26.5632
Si - 24.7315
thank you. I dont have an si product so I'll try agsil. I sometimes use power si in my foliar.
I've always aimed for 5.7 - 6.1. I would however soak the cubes in 5.2-5.5 water. what are you saying is the optimal ph range?

@nxsov180db and @im4satori and others, I'm hoping someone can help me to build out STEM a bit more. I picked up some Iron DPTA which is 10% and STEM is as follows;
All else is going very well. I stopped using Biomin calcium as it's not available for roots, just foliar of to leach out in soil. Still, am having great results with Cal Nit only. Also stopped using the humic/fulvic/kelp blend and my PH issues vanished. Just mix the weekly res with 25ppm of silica, and only 4ml on 10 gallons is needed and it's stable for 5-6 days.
Edit - I use STEM in conjunction with 5-11-26 and my targets are Fe-2, Mn-1.
- Sulfur (S) (Combined)…………………………………………………….13.00%
- Boron (B)…………………………………………………………………...1.35%
- Copper (Cu) (Soluble)……………………………………………………....2.30%
- Iron (Fe)…………………………………………………………….……….7.50%
- Manganese (Mn) (Total) ……………………………………..………….…8.00%
- ..................................................................8.00% Water Soluble Manganese (Mn)
- Molybdenum (Mo)………………………….………………………………0.04%
- Zinc (Zn)……………………………………………………………........... 4.50%

I've ran it in the app that way, but as I understand it, it gives me the amount of Iron DPTA independently which means I would have to make a jug of Iron. What I was hoping to do was mix a little more of the Iron DPTA in with the STEM, then mix that up as an augmented concentrate which would then mean I'll have to edit STEM in the app to account for the added Iron. As it is now, STEM is far from perfect and I have to settle with close enough. Well, I'm just trying to get that a little close, and as I said, I can mix a jug of Iron DPTA by itself, but I'm hoping I can skip that and just mix a little more of that into the STEM powder, then when I make a new jug of STEM, the increased iron is already in the mix.

That gets tricky as I have 5 different regimens for bloom to highlight different elements at different stages, so my Peter's usage fluctuates. I realize that after altering the Stem, my numbers will differ slightly chart to chart and that's fine, I just wanted to achieve a little closer than just pretty close. So basicly I'd have to analyze the STEM doses and average them out to see what's the best baseline number to use in the math, or even mid bloom as that's a 3-4 week period. What concerns me is how do I edit the values of Fe in the STEM substance details? If right now Fe is 7.5%, how would I bump that up to 8% or whatever number I end up with if the new product is only 10% itself. When used alone, I comprehend how it works in the app, but when trying to mix to make a new substance, how do I add in the 10%, and edit the STEM Fe value accurately?

I got lost in reading, but is the above the equation you did, or are those number arbitrary to explain how the math is performed? Knowing the answer to that will help me understand the math better.

Here is my mid bloom which essentially is used most in bloom, so it would give me the best baseline to work from. I targeted Mn to 1, and Fe to 0 so that HB would calculate the level of Peters to suit all of the macros, then it dials in the Mn with STEM and I notice all of the other trace elements look pretty good, leaving only Fe needing to be bumped up to around 2.
