I'm thinking I could use dry Koolbloom or monopotassium phosphate as a PK booster and get the NPK ppm ratio very close to 1:1:2
Why do you agree? Part of the reason I started this post was to learn. What do you think of my Maxibloom analysis? The initial numbers aren't PPMs, just ratios by elemental weight. I then applied the atomic mass of N to the N ratio (100) and came up with a factor of 1.61 to increase that number back to 100 (represents 100 PPM when mixed with water in the correct ratio). Each of the other elements has the 1.61 factor applied then is multiplied by each elements atomic mass. Coming out to 100-65-145-40-27agreed.
I agree because I've used lots of GH products and they all grow cannabis well.Why do you agree?
what grams per gallon are you using for your analysis?What do you think of my Maxibloom analysis?
Nothing specific in my math so far. One would mix Maxibloom to a particular ppm (maybe 750) and assume the N was at 100. Main point with the final NPK ppm ratios is that if you can achieve 100 ppm of N the other ppms will be at the stated levels. I'll try and work out grams per gallon necessary to get exactly 100 ppm N this evening.what grams per gallon are you using for your analysis?
if you calculate 7 grams per gallon but your plant is getting nute burn at 5 grams per gallon, you just wasted a bunch of time.I'll try and work out grams per gallon necessary to get exactly 100 ppm N this evening.
no offense... @Jennygrows2 but, she doesn't understand what shes sayingread this site. it gives the background of Lucas, some other nute recipes from other famous growers, and a nute calc at the bottom

I know that. I'm just theorizing on what it would take to achieve a 1:1:2 ratio (which is what some people seem to suggest for flowering). Whether it's worth doing is another matter. The Maxibloom schedule does list a PK booster, FWIW.in short
you wouldn't need to add mkp or any bloom booster to maxibloom.. its already formulated as a bloom enhancer and already has oodles of P and plenty of K
1. you can't assume it's 5% nitrate, you need to know what %ammoniacal, %nitrate.Maxibloom is listed as 5-15-14. For practical purposes I assume 5% nitrate. P2O5 is 44% P so 15 * .44 = 6.6%P. K2O is 83% K so 14 * .83 = 11.62%K
This gives us an elemental weight ratio of 5 - 6.6 - 11.62 (same as 99-130-230)
It doesn't make any difference in the calculator. 5% nitrate or 4.5% nitrate and .5% ammoniacal both yield 100 ppm at 7.5g/gallonyou can't assume it's 5% nitrate, you need to know what %ammoniacal, %nitrate.
Okay, so those are the values. I'd like to understand how they happen, because if I apply the elemental weight of P (44% of P2O5) and K (83% of K2O) to 5-15-14 I come up with the same ratio (5 - 6.6 - 11.62). Multiply by a factor of 20 = 100 - 132 - 232 (variance due to rounding P and K percentages to .44 and .83).and put 7.5 grams into the calc = 99ppmN, 130ppmP, 230ppmK. so the actual ratio is 1:1.3:2.3

exactly...perfect... you got itIt's as simple as that. I can use that information to determine that it takes 7.5g of 5% N to equal 100 ppm N in a gallon and that if P = 15% and K = 14% then the NPK ppm will be 100, 130, 230.
SO, now that's out of the way, how come there's so much P and K in Maxibloom? As I mentioned earlier, if NPK ppm ratio is ideal at 100:50:150 then the correct "bottle ratio" is 5-6-9. The only pre-mixed fert I could find with that ratio is granular. Jack's Tomato FeED at 12-15-13 can produce a NPK ppm of 100:50:200 using 3.125g/gallon. I will look into mixing my own, but I'm sure you can understand my being suspicious of 100:50:150 when there's not a single product on the market that achieves it except a granular tomato feed. If it's so great, how come you have to mix it yourself?
Now that my math is worked out I'm going to go back and analyse feed charts to see what the canna specific companies are wanting us to put in the water.
