water ppm?

[arthurjob]

right ive just run off to feed my babies some nut, after reading the stock ppm of my water it reads at 78, after adding superthrive and nut, it reads 161. ive read in places you have to have it between 650-750, shud i worry about that now as to get that high id have to add loads of food. am i mixed up? i only have a ppm metre atm, buying ec nxt week. thankyou for any help given


oh btw, my nut has a ph adjustment to it, does that mean i dont have to adjust it with ph pen anymore? i just add nut?

Since there is a known relationship between EC and TDS readings you only need a TDS meter.

There is a correct order to adding nutrients.

1. Take a small sample of your water and set it aside. Check your Ph and TDS so you know where you started.

2. Ph balance your water and let it stabilize.

3. Add your grow nutrients (if you are using a 3 part then itâ??s Micro, grow, bloom in that order)

4. let it settle again and check your PPM and Ph. Re-balance the Ph again if you need it but you should not.

5. Now you have your PPM you can add your Cal-Mag Plus, your B-1 or what other nutrient supplement you are adding.

For example if you are using GH 3 part mix and you want to give them week 3 veg feeding 1000-1400 ppm, light 18/6. You balance the Ph first then add 6ml pr gallon of micro then 12ml pr gallon of grow then 3 ml per gallon bloom is added last. Stir in all the nutrients and let it settle for about 5 min so the Ph buffers can balance out. You donâ??t want to play the Ph up and Ph down game you will only loose in the end.
