I've got a scale that weighs to the 100ths place, so thats good..
As far as your advice for the h3ads recipe;
I mixed 2g of each in 1 gallon of water. Each yield 450ppm for a total of 900ppm or ec 1.8
This is close to what I end up with also (1.6EC with R/O water in my garden on my meter). You will want to dilute your mix to 1.5. Do this by adding water or using less nutes than called for (i.e 4 gals worth of nute in 5 gal. of water).
From h3ads thread:
In the coco, I am now using 6ml/gal micro and 9ml/gal bloom which gives the nute profile:
N 97
P 60
K 105
Mg 41
S 27
Ca 97
adding 1 g/gal epsom salts to the solution changes the numbers for mg and s to:
Mg 67
S 61
ANDDDD from this jacks thread: https://www.icmag.com/ic/showthread.php?t=231574
1 gram of Jacks Hydroponic in 1 gallon of water = aprox
N=13 ppm
P=14 ppm
K=57 ppm
Mg=17 ppm
S=22 ppm
Ca=0 ppm
1 gram of Calcium Nitrate in 1 gallon of water = aprox
N=41 ppm
Ca=50 ppm
D9's Recipe i think is 1.6g jacks + 1.06g calnit to get 600ppm
64-22-91 = 3 - 1 - 4
So, by my calculations, 2 grams of each Yields
N=108ppm
P= 28ppm
K=114ppm
Mg=34ppm
Ca = 100ppm
N is a little high but the ratio is like 3.75 - 1 - 4..
Also, the P is alot less than that in the h3ads ratio..
Can you explain a little more..Im confused as shit
Also, do you mind showing me the difference between a plant that is too green, and a plant that is "healthy" by your standards.
Just wanna make sure we're not talking about different shades of green
You are correct in your calculations. Not sure what it is that you aren't understanding? Forgetting to factor in micro nutes (not listed in the recipe calculations) into final EC calculations maybe? As for the lower P levels, cannabis doesn't require nearly the P most people think it does. It can withstand a lot of it in the media without issue, which is probably why you see such wide variance in the available nute recipes.
keep posting those big pics, I hate having to click back and forth to see wtf is what. cool pics are the reason many look at these threads...I actually pay good money as a subscriber, so keep doin what yer doin. the thread is full of useful info as well, and I appreciate that info as well as full size pics. happy New year everyone!
no plans, I have small children, so they dictate everything I do.... be safe have a blast!
Take your pics in the dark homie
Im confused because the 2g/2g ratio is about the same w/ more N...(in terms of profile) (3-1-4 compared to 3.75-1-4)..
Aren't we shooting for 3-1-4, or I've even read that 3-1-2 is a really good baseline...
I guess in other words, Why does the extra N benefit coco plants, or what about the h3ad formula is better for coco than the d9 ratio. Doesnt the Jacks/Calcnit combo already have a little bit too much N?

Study CEC (cation exchange capacity), of coco specifically, and you'll understand better. Basically it comes down to coco's affinity for certain nutes (N,Ca,Mg mostly). Coco will literally pull out and lock up certain nutes until it's CEC is satisfied. The added N in h3ad's formula compensates for coco's need to lock some of it up for it's own purposes. d9's formula is designed for a low CEC medium that doesn't lockup nutes because there is little to no CEC to fill.
Again I'd like to remind you these recipes are not set in stone. They are merely a good baseline to work off of. Watch your plants very closely, they will always tell you when they need something
Oh and it's hard to see the overall health of your room with hps on. The pic of the single leaf shows nearly perfect health however, this is what every single leaf in your room should look like. If they don't, you have work to do.
