I am running Canna coco and nutrients, DTW, with a auto drip system. Just flipped and running 3 drip cycles during lights on.
I found this a few years back and have been using it since. Just have to adjust the Cal/Mag to get the required amount of Ca.
LESS IS MORE
200 ppm of a + b for veg.
350 ppm of a + b for flower.
Here is a chart the gives the ratios of Calcium in given ppm of A&B.
This Calcium information is purely based on a Canna schedule, using CaliMagic. Once you hit around 700 ppm you no longer need Cal/mag additives.
CaliMagic/Canna A&B ratio
150 ppm/200 ppm = 350
150 ppm of CaliMagic = 112 ppm Ca/200 ppm A&B = 44 ppm Ca, so, that equals 156 ppm Ca
100 ppm = 75 Ca/300 ppm A&B = 66 ppm Ca, that is 141 ppm Ca
50 ppm = 38 Ca/400 ppm A&B = 88 ppm Ca = that is 126 ppm Ca
This is based on slightly rough math but is very close to correct, in my experience.
A&B
3 ml/gal = .4 EC = 200 ppm with around 44 ppm of calcium
4.5 ml/gal = .6 EC = 300 ppm with around 66 ppm of calcium
6.2 ml/gal = .8 EC = 400 ppm with around 88 ppm of calcium
7.7 ml/gal = 1 EC = 500 ppm with around 112 ppm of calcium
9.2 ml/gal = 1.2 EC = 600 ppm with around 135 ppm of calcium
I use GH CaliMagic, and the RO is 55 ppm, it has Ca and Mag added back for flavor. I add Cal/Magic and Epsom to bring my #'s to 170+/- ppm, then begin adding the base nutrients. I use Canna Coco's line of nutrients but I back off of their recommended rates, as I feel they are way high. For example, in veg I will add only 200 ppm of A&B, in flower 350 ppm. Now that rate does not give me the Cal ratio needed. You need around 150 ppm of calcium alone, so even if when I'm at 200 ppm A&B = 44 ppm Ca, if I only added 100 ppm of CaliMagic, only 75 is calcium so I would still be short, need to add 150 ppm CaliMagic to get the Ca at 156 ppm.
5.8 pH & Drip Clean for the win!
