Ppm in veg phase? RDWC

[Grit99]

I know every crop is different, but what’s your rough ppm levels Week 3/4/5 in veg?

Also roughly how many Ppm does calmag and silicia add to nutrient mixture?

I don’t run RWDC but DTW hydro coco. About 1.0 -1.1 EC.

No idea about CalMag or Silica don’t use them, but it’s going to vary based on how much you use.

I never exceeded 1.5EC with DWC; your mileage may vary

1ml/G of GH Calmagic: 3N 13Ca 4Mg elemental ppm
1ml/G of GH Armour Si: 9K 12Si elemental ppm

Don't confuse elemental ppm with ppm displayed by a tds meter; they're not the same.

Yet another reason to stick with EC when you're discussing nutrient concentrations
