I am not sure if you are talking about elemental ppm N:K or NPK ratio on N - K2OAnd square. So I have high intensity lights and co2 levels. Not sure who wrote it but they said under these conditions, N has to double K? True?
When the light is more intense use 2x the amount of N to K. Example would be 200ppm N and 100pppm K
When light is less intense do the opposite: 200 ppm k and 100 ppm N
When it is hot out use less N.
They do make the distinction between WARM TEMPS and LIGHT INTENSITY. I would imagine in a typical grow room you are running low intensity light when plants are babies (i.e cloning) and high intensity all the rest of the time in a plants life. Temps would be average at around 75 degrees, as they say above 90 is "hot", so I don't see a need to ever cut N (until you are flushing it out in bloom).
My mentor has me getting a water report. I paid for two one pre filter and one post filter. $110 each. $220 total for me. Then either he mixes them or sends it to a company. I am soon to be rid of bottles
In what medium you grow?Hey all. I could use some assistance on my nutrient profile from hydro buddy.
I use a relativly inexpensive nutrient line from South Africa called nutriplex and was originally marketed as a Gen Hydro Flora series replacement with 3.5% Ca vs 5% Ca.
The nutrients have now been registered with the government and as such they are required to provide the elemental npk figures that have been lab tested.
Micro 5.0.1, Grow 2.1.6, Bloom 0.5.4
Sounds pretty good for a generic replacement.....
Now the elemental figures since being registered.
Grow = N 25.84g/kg P 4.32g/kg K46.23 Mg 5.82g kg - Sg 1.17
Micro = N 39.2g/kg K 28.5g/kg Ca 36.1g/kg B 0.205g/kg Cu 0.21g/kg Fe 1.65g/kg Mn 0.91g/kg Mo 0.079g/kg Zn - Sg 1.21
Bloom - P 18.7g/kg k 40.6g/kg Mg 29.6g/kg S 46g/kg - Sg 1.10
The Grow seems quite similar but the bloom and micro are way out once adjusting from Oxide to elemental.
Now I have made some Nutrient Profiles out of hydro buddy
Grow and Early flower are recommended at 1.1.1 per L
I get N 77.66, P 25.62, K 133.09, Ca 43.68, Mg 39.37, S 50.6 +Te
Flower 1.5,1.5,2 ml/l
N 116.5, P 48.72, K 222.18, Ca 65.52, Mg 75.33, S 101.2 +Te
Late Flower 1.2,1.3,2.5
N 97.94, P 70.61, K 243.8, Ca 56.79, Mg 94.51, S 126.5 + Te
I ask that some of you guys who have experience in diy mixing and nutrient proflies have a look and let me know if these numbers are accurate.
Is the Sulfur not too high? was considering running the standard flower and add 0.1g/L of MPK to raise the pk without adding more sulfur?
