Greenleaf does recommend a bloom booster with their Part-1. Given the above info, is it more appropriate, then, to formulate a bloom booster with Potassium Nitrate and Potassium Sulfate, or is that even necessary?
You don't need more P in flower. It's bad for your plants and the environment

High P also blocks or antagonizes Ca and K.

I have one organic amendment that is 3-9-3 which I thought was pretty cool, it also has a lot of minerals and micronutrients, but maybe Ill try to use it less. This actually came at a good time because I was a month away from ordering more of it.

I agree with the title of this thread, but also keep in mind that in terms of NPK values, the three major nutrients are not weighed evenly. See, the NPK values for P and K are in their oxide form (P2O5 & K2O), while N is measured in it's elemental form. To convert PK to their elemental forms, you have to do some simple math: multiply P by 0.43, and K by 0.83 to get their elemental weights. So your 20-20-20 nutes are really 20-8.6-16.6.

Thankyou for stating that. I was wondering my my 20-20-20 had different analysis panels.

I just learned it fairly recently myself. Here's a longer explanation I found on the internet: https://manicbotanix.com/establishing-ppm-in-solution-from-nutrient-labels/

K deficiency is what I usually struggle with for sure, but I never know whether its due to lockout or straight deficiency.

Don't know what your water's like, but too much Ca can lock out K.

Thanks OP!
Was using a 3-5-4 bloom which yellowed the plants too fast. Interestingly enough when mixed with the grow 5-3-3 it produced greener plants but lacked K.
Now I’m going to try outdoors just using grow then add there organic PK boost which is a 2-4-8. Should be a 7-7-11 ratio which should work for flowering.
I like P deficiencies as they are easy to fix/diagnose

If you want more K organically check out langbeinite.

Terrible...can regularly be upwards of 300-330ppm. And I probably overuse lime too. I'm assuming my heavy handed use of lime could be the culprit of my creeping interveinal chlorosis.

Oh ya. I'd cut out the lime. Too much Ca antagonizes Mg also.

I added a tbsp of lime per gallon (70/30 calcitic dolomitic) and then realised the organic 3:1:4 I'm using is 3:1:4 npk and 12% calcium. Oops..

I'm sure you've got it in your water too. Do you get Ca deposits on faucets and shower heads and stuff?

Yes lol. My kettle looms like a mine site..I've gotta make all the rookie mistakes sooner or later.

Citric acid works good to remove deposits from shit like kettles or shower heads.
It kills bugs too, and is a main ingredient in lots of bug killers. Or PM.
