Another question that has occurred to me is the fundamental difference between a CF and EC meter. They both seem to measure the ionic content in the water.
hi byte
this chart will you an ideal but never really looked into it before
i us a ec truncheon and find 1.3 seems best for my plants as 1.5 tend to get nute burn
i keep things as simple as i can just use bio buzz grow and bloom,Epson salt
i don't flush my plants till the end, a week before harvest
i do not move the plants in flower
just lift the front pots to see if they need watering
get your room set out the best you can before you start growing
