ATP, Adenosine triphosphate is the result of respiration. When the plant breaks down glucose, produced during photosynthesis, the ATP is the energy the plant literally uses to grow.The claim was that P powers N through the plant. From what point to where im not sure....i cant remember the literature i was reading..is ATP created with P as the center molocule?

All plant need P, a good reference for ppm for an aqueous solution is Hoagland #1. Dr. Hoagland developed a great hydroponics solution decades ago and will produce outstanding results.
Not too surprising when you think about it. All they're doing is finding out why the things learned through millennia of trial and error work. Lets them try to find new and/or more efficient ways of doing things. Not to say that's always better, but trying to find ways to reduce or eliminate waste in the system is a good goal.Funny how not much has changed in nutrient profile with all the science tested since the 50’s

A long webinar but loaded with extensive knowledge on phosphorus.

Plant nutrient needs do not change because of the medium used.
Cal mag and limed peat will do totally different things. Managing either is different than the other. Managing organic soil is obviously different than other mediums. All I’m pointing out is the ppm plant needs do not change based on the medium. How to achieve those levels changes.no but what need to be done to manage the medium can.
coco needing cal mag added while limed peat mix does not for example.

This thread got me to try to see what PPM's are in my existing commercial nutrients (veg bloom powdered nutrients) and test if I could get as close to these ratios as possible without mixing my own salts. Hydrobuddy and Angelfire both offer the ability to do this but it seems that the conversions on P and K are totally off from eachother. Does anyone know which one to go by or if maybe I am using hydrobuddy or angelfire incorrectly?Honestly like stated and I do the same... K 200ppm, CA 100ppm, Mg 50ppm. This is why I use only mag sulfate in addition to my tap water because it much higher as most are in CA than Mg. So between my nutes and tap I have enough CA and lack Mg.
100-120ppm nitrate, P I keep around 30ppm
Ratios..... its all about the ratios.... N to K 1 to 1.5/2, K to Ca 2 to 1, CA to Mg 2 to 1, Mg to P 2 to 1.
Adjust the ppm and should not have an issue. Most problems start when ppl start throwing in all the bottles of unicorn piss that all have the same shit and throwing their ratios all out.
There is a way to look at available tattoos and input ratios... that could be the difference.This thread got me to try to see what PPM's are in my existing commercial nutrients (veg bloom powdered nutrients) and test if I could get as close to these ratios as possible without mixing my own salts.

I just use the "substance analysis" button and enter the label information there. The only thing that confused me was it is defaulted to milliliters per gallon for the volume of addition. But I am using powdered nutrients and am unsure how to change it to grams or if this even has any impact on the way it converts.
The P is 80ppm in hydrobuddy and 29ppm in angelfire (for 5g/gal)
The K is 171ppm in hydrobuddy and 143ppm in angelfire (for 5g/gal)
Everything else was fairly close but the P especially being converted at such different numbers seems a little worrisome.
