Those are very similar to the nutes I use. What seems to be the issue? I don't weigh my nutes but measure them. 1/2 tsp of vegetative 7-15-34 + 1/2 tsp of the Cal 15-0-0 + 1/4 tsp of the Mag per gallon should put you real close to 1.6 EC / 800 PPM. I just weighed some calcium nitrate and 1/2 tsp weighs right at 2.6 grams so their feed chart is pretty close to the numbers you should be getting. Are you factoring the ppm of the water you're using?
I'm sure those nutrients will grow good weed and are much cheaper than AN but the Cal, and Mag are complete ripoffs and just repacked calcium nitrate and magnesium sulfate.
The veg at 7-15-34 for $70 for 5 lbs is so close to a product like Jacks, Peters Professional, or Masterblend 5-11-26 that you wouldn't notice any difference using any of them but the 3 I mentioned cost $45 for 25 lbs. That's somewhere around 8 times cheaper.
The Cal which is just calcium nitrate at $45 for 5 lbs can be had for $40 for 40 lbs.
The Mag is just magnesium sulfate "epsom salts" at $45 for 5 lbs can be had at any drug store for $4 for 3 lbs or you can also buy $50 lb bags for $25.
I wouldn't even bother with the fruit and flower myself and just use the veg all the way through or vice versa. There really isn't much difference other than slightly less nitrogen and a little more phosphorous in the fruit and veg. But not anything significant.
I think you made a wise choice getting away from AN's bottled nutes and these will save you some money but they are way overpriced. 2 of those parts are just repackaged and marked up 5 times. 5 lbs of epsom salts for $45. That's completely insane. And their blend of nutrients is nothing new. Basically the same formula's used by Jacks, and many others for decades. And now copied by MegaCrop. But if people want to pay the prices they're charging I can see why they're charging them.
Good luck.
