Gyo…I’m proud your putting forth the effort to do some research…The Krebs Cycle is actually the way all plants, animals, and even bacteria produce energy…(although some anaerobic bacteria have altered it a bit).
Clarification…1.2gm/L = 12000 ppm (0.001mg/L=1ppm)
I’ll give you a interesting fact about K That many people don’t understand. As animals (and all animals) we use Sodium (Na) as an electrolite which is ideal for us because guess what, we have kidneys and a urinary tract to remove excess sodium…plants don’t…so they utilize Potassium (K) for the same purpose (electrolite). Here’s a little problem for plants…If you look at the Periodic Table of elements, you will see that Na sets right on top of K in the same column. That means that sodium is more reactive and can easily displace potassium, but potassium can’t displace sodium.
Now take that fact and consider this… Your plant roots are (for all intents and purposes) immobile in the soil. (yes I know the roots move through the soil, but the point is they can’t pick up and move if they find themselves in a inhospitable media.) Next thing to consider is that again because they are so close together in the Periodic Table the size difference between a Na atom and a K atom is miniscule. Roots CANNOT differentiate between the two and will passively absorb both directly related to the sodium/potassium ratio in that local soil (media) solution. Sodium in fact mitigates (blocks) Potassium’s important role in a tremendous number of oxidation/ reduction process’. Because plants have no other way of eliminating sodium, they will move it to the leaves, which of course burn and die…but guess what they fall off the plant and the plant got rid of a bit of sodium!
Point to the whole story is you want to keep the plant exposed to the minimum amount of sodium possible!
(Now I know someone is going to look up Sodium as a nutrient and they will find there are some cereals [barley?} varieties that seem to have some Na requirement) But I’m guessing most here are interested in cannbis, ornamentals, or fruit/vegetables…and certainly if you want to maximize your plant health…minimize the sodium ! (one of many reasons R/O or distlled water is so important in mixing your nutrient solutions and irrigating your plants FWIW
I do applaud your research as there are so many amazing doors opened to you with knowledge!
Good for you!
Please understand I’m trying to make valid general points without wading into the excentricities.
FWIW
