Been trying to see exactly what PPM of every element that I'm using to try and figure out some things. I've read some very confusing things about how to calculate this and I see a lot of debate over it. I basically use:
6 mL General Hydroponic FloraMicro (5-0-1)
9 mL General Hydroponic FloraBloom (0-5-4)
I use these rates per gallon and my water is 140 PPM from the tap. When I mix up a gallon with my formula, it reads 740 PPM. So when I subtract my water, I would get 600 PPM. Now I need to know how much of each element in PPM that I'm getting. I know in reality I need to know the weight of each element but I would think I would get a decent estimate with this equation by just estimating every mL to be a gram
(even though it is not always the case):
1 Gal of Solvent (Tap Water) = 3.79 Kg
6 mL of GH FloraMicro = 6 g
9 mL of GH FloraBloom = 9 g
1 g = 1,000 mg
To find the PPMs for FloraMicro:
To find PPM of N:
{6g (6mL of Micro) x 0.05 (5% N) x 1,000 (mg)} / 3.79 Kg (1 Gal)
N = 79.2 PPM
Ca = 79.2 PPM
K = 15.8 PPM
B = 0.2 PPM
Cu = 0.2 PPM
Co = 0.01 PPM
Fe = 1.6 PPM
Mn = 1 PPM
Zn = 0.24 PPM
Mo = 0.013 PPM
Total FloraMicro = 177.5 PPM
Now when I do the same thing with the FloraBloom and put 9 g into the equation for 9 mL Bloom per Gallon, I get:
P = 119 PPM
K = 95 PPM
Mg = 36 PPM
S = 24 PPM
When I combine all of these totals, I get 452 PPM and then when I add my 140 PPM water, I get roughly 600 PPM. Is there a better equation that I can use so that I can find where my loss of 140 PPM went? Seems like I'm doing something wrong.
