2-part AB bloom NPK numbers by brand

I was looking at a bunch of different 2-part AB bloom nutrients today.
I compiled a list. There's a few powdered nutrients on there too.
A few common ones aren't on this list.
Either the numbers were hard to find, or I've used it before, and am looking for something new.

I've been using the first one on the list for a year or so, the Yellow Bottle Euro AB.
Drain-to-waste, Sunshine Mix #4 (also used it with coco).
I think it may have a bit too much K.
That's why I was looking at other nutes.

Anyway, here's the list.

Bloom Yellow Bottle Euro AB 11-7.2-18.8
A 9-0-7
B 2-7.2-11.8
*My calculations show that cutting part B by 25-35% makes it closer to a 10-5-15.
I will try this.

Cyco Bloom AB 4-5-8
A 3-0-2
B 1-5-6

Elite 4-5-5
A 4-0-1
B 0-5-4

Emerald Harvest Cali Pro Bloom AB 4-4-9
A 3-0-3
B 1-4-6

GH Flora Duo 6-5-10
A= 5-0-6
B= 1-5-4

Growth Science AB 5.5-6-4.5
A 5.5-0-0
B 0-6-4.5

Mills 3-4-9
A 3-0-6
B 0-4-3

Nutri+ Nutrient Bloom 7-4-11
A 6-0-3
B 1-4-8

Remo 6-7-12 (3-part)
Grow 2-3-5
Bloom 1-4-6
Micro 3-0-1

* I also added some powdered nutrients

Jack's 20-12-26
A 5-12-26
B 15-0-0

Jacks RO 12-4-16 (1-part)

DaKine 420 (looks like a copy of Jack's, Base is A and Grow is B)
Base 3-13-26
Grow 14-0-0-17Ca

Cyco Commercial Bloom (1-part)
8-6-11

Here's a really simple way to manage NPK ratios. Micro + Bloom in equal parts give 5-5-5.

From there you only need to adjust PK + Mg. If you use LKB (0-10-10) for example as a bloom boost and add that at half the ratio it should give 5-7.5-7.5. The math may need to be checked on that but hopefully you'll get my meaning...Adjusting the ratios to tailor your specific grow is possible.

More cut/boost calculations with the Bloom Euro AB.
Cutting A by 35% and boosting B by 20% changes it from 11-7.2-18.8 to 8.2-8.6-18.7.
This is a 25% drop in N, 20% boost in P, with practically no change in K (it has plenty).
I'm going to try this, instead of using a PK booster, in week 4 of flowering.

I'm switching to Jacks 321 two part based on recommendations from Greengenes Garden (YouTube). You might want to check out his excellent videos. I was curious about the Jack's one-part since I'm using RO but I prefer flexibility over convenience. $152 for a lifetime supply. I'm hoping this will also help with the pH drops. I've been adding Cal-Mag even in bloom with my GH FloraTrio just to maintain better pH stability in my LPA system.

I'll add MKP as well to actually follow Greengene's formula.

Sorry for the late reply, I've been logged out for a while. Changing the ratio instead of using PK boosters did tweak the leaves a bit, similar to how PK boosters sometimes do. I can't comment on yield though, because I was running the LED lights too soft.

Now I'm running the LED strips on higher powered drivers, and the bud development is much better. I'm using a different base nute (Greenstone Nectar AB). I keep coming back to this stuff. My mother plants like it (1:1 N:K ratio is good for moms), and it works for flowering too. I think the even 6-5-6 ratio keeps me from getting into trouble with nutrient lockouts and stuff. I've been using AN Big Bud weeks 2-4, so instead of cutting just the A, I cut both A and B this time.
