Their charts and all of nutrients charts are recommendations.
I use synthetic nutrients and what you are using. They are good.
So just go by PPM. Just cause they suggest using 2ml/l for every week. Doesn't mean you do. It's just a rec so you adjust to suit your plants needs.
Water for 1st few days.
As you go into Veg, if you're using soil you can wait for a few weeks. (Just enzymes, with no EC value)
But if not. You shouldn't have to exceed 4-500,ppm of grow for your entire veg. And push it up to 700 or around that in later stages of flowering.
Follow what your plant shows you.
Good luck
