I'm with ya on this.
Except for the micro nutrients, no desire to chelate my own.

Excellent hydro buddy primer. I've enjoyed it in the past. And will probaby revisit next time I get the urge.
Hydrobuddy only does what these spreadsheet calculators do...right? Just wanted to make sure.

Well, my spreadsheet is home grown, just a collection of numbers for products I use, from places like Greenleaf, Angelfire calc, hydro buddy, @Renfro etc......fancied up to work for me. Since I go back to Lotus 123, I forgot more than I can remember about spreadsheets. :p

I was just dicking around with a Jacks clone using MC.

I remember MS Spreadsheet for my old Apple II. lol Came in that cool smokey grey plastic box. Man it would seem so primitive now.

I bet you were doing this at the same time as I was, the other day, lol.

I decided to have a second (eighteenth) look, and rewatched/read a couple things, compared profiles. I don't know why I was so focused on that 100-100-200-60 profile - I liked that it had plenty of P though.
Anyway, I looked at jacks and noticed it's not even that high in P compared to, say, megacrop at all...

When I enter the info you have there in your spreadsheet into RenfroCal v2.04 (lol), I get this:
Calculated
Elemental PPM
Nitrogen (N)124.4
Phosphorous (P)47.3
Potassium (K)198.7
Calcium115.5
Magnesium79.6
Silicon0.9
Sulfur101.2
Chlorine0.0
Sodium0.0
Iron2.3
Molybdenum0.1
Zinc0.7
Manganese0.9
Boron0.3
Copper0.5
Cobalt0.0

I duno why this table is so damn huge...

I don't chelate micros, I buy them already chelated. I can then mix them to GH's Flora Micro formulation, or Jack's/JRPeter's micro formulation, my own formulation, Megacrop's micro formulation, but the concept is the same as macros. IME, a micro regimen remains constant throughout the grow and it is only the macros that are adjusted, if at all. When you mix your own micro concentrate, you are completely free to target your macros with great precision. I achieve my macro targets 100% of the time, but only because I first did the same to the micros and whipped up a half gallon of concentrate that itself will make me 500 gallons of reservoir. FWIW, I'm now running Megacrop Vegan with Calmag, except I didn't buy either, I just used all my own salts that I buy for a fraction of the cost of any one nutrient line. No bullshit, you buy one gallon each of GH 3 part with all supplements, and my salts cost less, I have 100% control, and they'll produce more nutrients than the 1 gal of GH, a LOT more.

In my 420 thread, there is a Bill of Materials on the top of page 3 and all products listed comes to under $200 before shipping from the midwest including all needed chelated micros and enough macros to last a year more or less. For comparrison, I use 40 gals a week. I started out with Jack's, I made this thread, and my growth can be tracked on this site as it is here wher I learned, mostly from @im4satori and @nxsov180db though I took it to the furthest extent I could. I wasted a lot of money searching for the cheapest most workable products and 99% of it comes from Custom Hydro Nutrients. I have plenty of products that I will not use, like the rest of Jacks and Peters, plus all of the metallic sulfates are trash unless I score me a farm one day.

If you're gonna go with Jack's or Megacrop, it don't matter, with salts you can try them both and still have the option to try other things. Its a no brainer IMO.

Hydro Buddy and spreadsheets are both programmed to handle the various math problems to calculate elemental ppm. IMO, the spreadsheets have the potential for unlimited functionality, yet Hydro Buddy was created by a skilled botanist. His lack of coding skills is evident in the way his app is laid out, but I do trust his math, plus it has a nice big database with common reagents already recorded as well as a plethora of formulations already programmed, but still there is a limited number of elements considered, so the app is restricted in that regard. It's a tradeoff either way.

If you dont mind me asking at what strength are you using Jack's hydro

One thing that could be done when adding a PK booster is simply add it and then cut the mix with water if the PPM is higher than desired.

Do you mix in all the extra ("bio stimulants") that mega crop has in it when you make that/have made that in the past? It must be crazy all the bags of stuff, lol. Chitosan and everything?

One of the things I'd never thought of until recently about cutting the base (for example MC) is that you also cut all the micros.

No, though Custom Hydro sells most of those biostimulants as well, but that's another topic. All I add outside of the salts is a soluble blend of fulvic, humic, kelp that I get from Kelp4Less. FWIW, I also use foliar sprays, and I add triacontanol @ 5-25ppm every other spray.

Same, lol. Plus their yucca and amino.
I don't think CH sells to canada, so they don't exist.

I used to use the Aminos too but found my plants slowed down their grow speed. Now I only use the AA in my foliars.

I'm following a Canadian that's in the same boat as you, unable to track down good materials up there and getting murdered with shipping charges from CHN. You can track down certain salts up there, but ultimately you're going to either have to bite the bullet and pay the insane shipping charges to get the materials, or keep buying branded nutes. IMO, your best bet is to just get Megacrop Vegan and either Greenway Calmag, or Botanicare calmag if you don't mind buying water, but both have the same formulation except one is wet, the other dry. Those 2 products alone will set every grower straight. I am very impressed with my reformulation of MC with CM.

I used STEM which is the same as MOST, and both suck IMO. Best bet is to buy chelated micros and mix your own blends.

Can you elaborate what it is about those products that you dislike?
They're made from sulfates which means you can't mix them into concentrates which means you have to weigh out your needs each week which involves a dust mask at least. I favor going through all of that once to make a liquid concentrate.

Also, if you desire to change the formulation, you can't. It's either add more or add less, but no tweaking. Having all of the micros individually enable you to control how much is added and thus you control the blend.

Makes sense. You have a list of the micros you like to use?
