1 gram is usually very very close to 1 ml. If you want to be more specific (which I don't think is necessary) weight out a 100ml of whatever liquid nutrient you're trying to use.
^hes better with hydrobuddy than I am, I rarely use that particular program

As far as I know, HydroBuddy is the only free nutrient calculator, and there's definitely some quirks in it's formatting, but it is free so I'm not bitching. I tried combing the web for density details of Amor Si, but was unsuccessful. I found density values the other day for other products, and also found the density to be right around 1.00, slightly above, so I suppose that's enough to rough it and register that nute as a dry in the app.

im4satori, would you kindly think of what you consider your safe ranges for the major elements in a Veg regimen? Just as long as the numbers are close enough, they would give me the ability to better understand the tolerances and I'd know how much freedom I have when tweaking the recipe. This is important to me because as time progresses, and I get more invested, I will have that much more product that I'd want to squeeze in there. Also, when I'm done with Jack's Pro, I'm leaning towards trying the ChemGro 4-20-39.

Why not just measure out a 100ml of your liquid nute, if it weighed for example 110 grams than you know 1ml would be equivalent to 1.1 grams. Most everyone just assumes that their liquid nute weight 1 gram for 1 ml, its always going to be very close.
i ususally go with the 1ml for everything also

I'll give this a whirl and see what's what. Thanks for the tip!

veg range

N 110 -120
P30-40
K 120-130
Ca 80-90
Mg 40-50
Thanks so much for this. Is there a low value for Iron(Fe)? I doubt I'd need to know the high as I do not intend to raise EC.

I like to see my iron around 1.8ppm but you can go as low as 1.3 and likely not have any issues

but that's also debatable since im not exactly sure how much im getting from my source water

Getting the correct ratios is trickier than I thought, especially when trying to land in the ppm ranges of my meter. I wonder if it would be better to purchase individual Macros and some MOST for micros to have individually specific control of at least the macros?

Here's another remix of veg. The best I could produce with hydro buddy was slightly less N and slightly more Ca, but it seems I can't bring both into the desired ranges.

that looks good

I think what your looking for for this mix to get your numbers closer to what your target is would be the addition of magnesium nitrate and the removal of Epsom

thatll give you the magnesium you need and boost the N instead of the sulfur which is what Epsom salt does
I believe the magnesium nitrate will get you where your trying to go with your veg numbers
try this out


1.6 grams calnite
2.25 grams jacks
0.5 grams magnite



as far as mixing each individually, that's what I do! I mix each element
for my concentrates I add each micro nute individiually but if im doing a direct addition mix (meaning I weigh it and dump the weight directly in the reservoir to create a finished solution and not building a liquid concentrate)
in that case I will use peters s.t.e.m. for all the micros

mix rate 0.1 grams per gallon

peters stem is a micro mix blend similar to the 5-11-26 on it contains only the micros


also, don't forget, ig your ph adjusting with phosphoric acid then your adding P

phosphoric acid
0.25mls ph down per gallon adds 3ppm
1ml ph down per gallon adds 12 ppm

I'm finding with what I'm using that I mostly am in need of pH up, so it's PotSil, of which I only needed 0.2ml added to get to near 5.8. I'll look to get some MagNit as well as a stable (non sodium) Calcium.

Edit - Is 3-1-3.6 good for Veg? Most archived threads I've read are saying 2-1-3 for Veg.

2-1-3 is good for most or all of bloom, its kinda a middle ground ratio between the far right and left lol
it might work for veg for some depending... its certainly fine for soil at any stage both veg and bloom

110-35-120 veg
90-45-130 early bloom
75-60-130 bloom
65-65-130 late bloom (lucas formula)


watch the numbers as if a wave or in motion

N is dropping, P is rising, all the while EC/active elemental ppm remaining roughly the same

if you add the sum total of each formula the total is roughly the same

for example
veg
110+35+120 = 265
early bloom
90+45+130 = 265
bloom
75+60+130=265

so the strength of the mix remains the same +/- but the ratio of P vs N keeps changing

this example only shows the NPK numbers and doesn't include the other elements such as calcium and magnesium or sulfur... but you get the idea

after you factor in the rest of the elements I usually end up around 450 total elemental ppm (again, not at all the same as a ppm meter) at max feed which is usually around EC1.2 for me and my environment

I'm trying to research why elemental ppm and meter ppm differ, but am unable to track that down, so all I have to work with now is my speculation. I'm guessing that for instance, CalNit is 15% N and something like 18% Ca which together totals 33%. That doesn't account for the other 67%, and it is that other inert, uncharted material that I suspect is causing my meter to output much different numbers than Hydro Buddy as HB is unable to comprehend this other inert material.

Is that about right?

do some searches on EC vs PPM and the difference

figure out how your meter gets the "ppm" reading

really..it shouldnt be called PPM (meter) as its not truly or actually ppm at all.. the whole thing is kinda stupid and confusing

jesus if u cant work out simple nute ratios u should not be growing

I know how to relate EC to PPM and vice-versa, and I assume the electronics in my meter perform the same math, just don't why they disagree so much.

!
think of it for a second like this

if the world didn't have ppm meters the world would be a better and less confusing place
why anybody decided they need to convert EC to a fictitious PPM at two different conversion rates should be shot

ppm on a ppm meter isn't ppm and doesn't measure parts per million and therefore shouldn't be called ppm

theres is no way to rationalize the two readings between your meter ppm and the active elemental ppm as there not at all the same thing

the meter ppm simply converts EC... and that has nothing to do with actual ppm within the solution

for the sake of conversation I would only refer to ppm as elemtal ppm and EC as EC but I would prefer the ppm readings from an EC converted meter to not exist or be part of the conversation because the whole system is stupid

but in short
PPM from your meter is not actually part per million....

Ok, another way I could ask this is if HB outputs for example 1 = EC. On my meter, this would translate to 500. When I mix the recipe, my meter reads 750 which then translates back to EC=1.5. TBH, I wish PPM meters didn't exist either and I'll go ahead and find an actual EC meter, but I suspect an EC meter would still return 1.5. It's those differences that I'm stuck on.

FWIW, when I mix and adjust, I always do things in 50 ppm increments on the meter, so EC works just as good for my needs.

if you know your meters conversion you could try and do the math backward but honestly its not going to line up so id not get stuck on it

even with hydro buddy and comparing EC.. the EC amount hydrobuddy says doesn't always line up with my EC meter

i use the meters as a bench mark/reference point to see if the EC in a solution is rising or falling comparing the feed solution to the waste in dtw or comparing to the last reading taken in recirc

now that you've advanced to using the math and elemental ppm youll not use your EC/PPM meter to reference solution strength but instead only to EC changes over a given time and more as a bench mark relationship
