Mixing your own from powders would save you a ton of money over the ready made stuff you normally would find at a hydroponics store. Works just as well if not better and you get to control what you put into them.
My General Purpose Recipe:
1 gal RO or distilled water
600 grams Masterblend 4-18-38 Tomato Special
300 grams Epsom Salt
1.5 grams Sodium Benzoate as a preservative
1 Gal RO or distilled water
1,100 grams Calcium Nitrate (YaraLiva CALCINIT)
The above would make a 250x concentrate (each gallon of concentrate would make 250 gallons of working solution).
I use it at 15ml part A and 15ml part B for each 1 gallon of water.
With RO water you would get an EC of about 2.0 or PPM of 1000 at the 500 scale.
Working strength nutrient breakdown (approximate):
N – 203 ppm
P – 50 ppm
K – 200 ppm
Mg – 45 ppm
Ca – 220 ppm
S – 50 ppm
Fe – 2.5 ppm
Zn – 0.63 ppm
B – 1.27 ppm
Cu – 0.63 ppm
Mo – 0.063 ppm
Mn – 1.27 ppm
Cl – 12.7 ppm
Hope that helps. Again, this is not a fits all solution, just what I use personally, feel free to change the recipe to your requirements as needed.
