I think
@gr865 is feeding around the 750 range? Somewhere close to that I think
Some guys are floating up as high as 1100-1200, others keep on the lower side, it all seems to work lol
I would imagine it would also be strain dependant on how heavy feeders they are
I don't really consider the final number for ppm, I look first at my base nutes the rest is what it is, unless your adding a bunch of N in other forms.
This is from my Less is More post. In veg I will add only 200 to 250 ppm of A&B and in flower 300 to 350 ppm. Now these rates do not give me the Cal ratio needed. You need around 150 ppm of calcium alone.....so even if when I'm at 200 ppm if I only added 100 ppm of Calimagic, only 75 is calcium so I would still be a tad short. In flower, I use RO (55 ppm of Cal/Mag), to this I add 0.75 ml Cal/Magic (68 ppm) and 0.5 grams Epsom (63 ppm) per gallon to bring my #'s to 131 ppm, below the 150 ppm needed, That's without the 55 ppm of the RO and that gets me close to my number, then begin adding the base nutrients. I use Canna nutes but do not reduce the additives, Cannazym, Rhizotonic, or Boost (use their mid range).
This is my worksheet from today.
This worksheet is for the 7th week of flower, so things have been adjusted to meet my needs. Extra Epsom and CaliMagic, as I have had some deficiencies. I also replaced Canna B with Dry KoolBloom at reduced rates. This is my third rez with KB, used .5 grams in the first two rez's and .25 in this rez I made today. I get 4 days per rez fill with the last day a mini flush of about 4 gallons plus Great White. I raised the Boost by 1ml/gallon.
I get a total number at this point of my grow of 571 ppm or 1.14 EC.
There are points in my grow where I may be around 700 buy try to keep it below that when I can.
Diggs you are correct with some or 1000 plus but I try to not over feed and send my high $$$$ Canna nutes down the drain so to speak. My waste does not go down the drain, it feeds my yard and plants.
