Hydroponics and EC

Whats a good Ec to give them on week 1 just rooted, a know every strain/plant is different but roughly how much?
There OG Kush

Heres some charts that may help:
PPM for Hanna Chart 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

So .2 ms/cm would be a good starting spot.

thats spot on them had it up a little high, thanks for the info

for babbies i keep ec below .5
