GLN says 1.5:1 A:B 2 part is closest to the 1 part
Seems short on N to what the 1 part is. I am running about equal parts and plants seem lighter green. Not using their brand cal-nit but I would rather be a little shy on N. I am making up the calcium with pickle crisp. What I cant quite place is the difference in iron? When I was looking at the maths it seems as if there is some iron impurity in their cal-nit?

the ratio is 1: 1.125

That's the base nutrient mix in RO water with General Hydroponic PH up added to 5.7-5.8 (not much) nothing else. Puts me at 1.4-1.5EC. I am with SS on the response from GreenLeaf that 1.5 : 1 is pretty light on Nitrogen and it's hard for me to believe that's accurate to the 1 part. But, I only used the newest 1 part on vegetables this year.

Most of my con


If the plant eats 50ppm how do you see that on EC scale?
You don't when using EC at that scale but it can. Meters can display EC as a whole number 1.4 = 1400. PPM meters are using what they display calculating from the electrical conductivity of the water and then display it as a number depending on the scale( 500 or 700). Why not use the actual electrical conductivity that the PPM meter is using as your guidance.

Resolution. When I was trying to get 30+ days on a res change. As @dstroy0 has pointed out one flaw with that is accounting for root exuduates.

The way I understand it is 500 is the 1 to 1 ratio 700 was set up for drinking water quality to base off CaCO ??
I believe it's more like a 1:2

"To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1*1000/2= 500 ppm."

Kinda why I ditch the PPM, it's using EC as its base number. No need for anymore mumbo jumbo in between me and my accuracy.
