I'm going to run Jacks Nutes RO formula in pro mix hp. Feeding every 48 hours or so. Should i stick with their recommended ec of 2.3 or should i lower it to 1.8ec because of the 48 hour dry backs. My thought is the dry backs would concentrate the nutes in the medium.

Pot size, plant size, vpd, growth rate and any other variables will dictate what you do. I like watering every day and starting at 3/4ish strength to begin with.

I've used it to veg cannabis and for container herbs, never went over 1.3EC and everything was dark green.

Start a bit lower than recommended and see how they react. It's easier to overdo it.

Cut that recommended ec to half use it every watering with good runoff, got to be careful with dry back with promix What size pots? I run 3 gal an water-feed everyday.
