New Grower EC TDS Levels

[temple_of]

Hello, I am trying to find some more info about EC and TDS ideal values for watering ( soil growing ).

I just found on the internet recommended EC values:

Seedling 0.8-1.3
Clone 0.5-1.3
Vegetative 1.3-1.7
Flowering 1.2-2

is there something similar for TDS?

ok I think I got it, TDS:

• Nutrient Water: 400ppm - 800ppm total

Alot depends on medium,lights,etc..i kno i get mine much higher then 800ppm.im at that a wk after mine drop roots.almost double that in flower actually....

thanx for your response, I found another info regarding ppm

Seedlings, Early Sprouts 100 to 250
Early Vegging 300 to 400
Full Vegetation 450 to 700
Early Blooming 750 to 950
Full Mature Blooms 1000 to 1600
(this excludes the ppm of your water)

water is about 400ppm, so all values + 400

To convert ec -ppm you multiply ec value by 1000 and divide by 2.to convert ppm do the opposite.take ec value multiply by 2 and divide by 1000.

Ya thats a lil closer to what i do..full on veg im at 1100.full bloom im 1440..alot depends on strains tho.in i grow photos in they handle more.i wouldnt suggest reaching these hieghts with an auto..if its first time growing yur strain up it by 200 a time so u can easily back off without overdosing

I just read it that tap water cca 400ppm.. I will check it and send the value.. not uk.. but central eu.

The tap water where I'm at runs 500 ppm! So I've been experimenting with how much I can add, using the GH nutes and a couple supplements (which ain't much at all) in my bucket before I officially try out my new waterfarm for the 1st time. This could get interesting.

What means GH nutes?
