Haha, cause that's what this thread is about? Maybe I'm not understanding correctly.
Just curious what your elemental mole ratios are and what compounds you're calculating from, ie if you're equating 1mole of P2O5 into 1mole of available P, ect. Looks like you had posted pics with all the basic nutes the plant would typically want, ect, so I'm just curious what the ratios were/are so that I can get an idea and replicate myself. Who knows what's in the bottles these companies sell. I'd rather know exactly what my inputs were ect than using a companies A,B,C line and blending blindly.
Ppm just tells you conductivity, it doesn't really tell you the actual % composition. PPM meters can be less than accurate and are dependent on water temp ect. I'd rather build my solution by weighing out the salts as opposed to relying on a PPM meter to tell me when to stop adding ect. Then once the solution is constructed, sure use a ppm to tell me differential concentration (ie if plants are consuming and how quickly).
I'm just after the recipe or ratios you're suggesting or talking about and also what conversion factors you're using in the numbers provided, ie if a % element, or ppm element, or weight element, ect, is actually representing an equivalent compound.
If % P was actually % P2O5, then P would actually be twice as abundant as the equivalent P2O5 would try to tell us.
There's 2P in P2O5, and only 1P in P, so if we were to compare the amount of P in 1 molecule P2O5 and the amount of P in 1 atom of P, then the atom of P only has 1 P (duh) and the molecule of P2O5 has 2 P atoms.
If you told someone that your solution had % weight of P equal to 25%, and if they tried to replicate without knowing that the 25% weight of P was actually equal to 25% weight P2O5, then the person will not accurately replicate the ratio you told them, they'd end up only putting in half the actual P compared to what was intended.
Lots of weird and gimmicky ways that companies list nute concentrations by, so just tying to understand from an elemental standpoint what your pics are saying. Just trying to interpret them correctly. Seemed you had some knowledge and Im just trying to pick your brain and curious as to all the nutes you thought were important and what your ratios were, or what other peoples ratios were that you've stumbled across, or even just anything you've found to be significant ect.
