Measuring EC

Like yourself E.C i do not bother with just use it as makers recommended on the bottle then adjust as i go through the stages. PH i do not do that either self PH ing nutrient puts it to around 7 so its sweet asa nut to me. a lot depends on how you grow also your own experience if you have not done this before learn to watch your plants they tell you everything A little less is better than more same goes with nutrients getting lots of different types generally ends up in confusion and damaged plants keep it simple goes a long way
