I am about to start my first grow and will be using Jacks 321 in a 5 Gallon DWC System. I have been reading years of posts and have a few questions I can't seem to find the answer to. I will be using tap water that has around 130 ppm taken with the meter I purchased. Most of the information I have found says to use a PPM/EC meter for a final reading of around 600 with RO water.
If using tap water with a PPM of 130 what should my readings be (would it be something like 730)?
I see the recommendation of using a PPM meter so you don't have to measure however I don't see the numbers I should have after the addition of each ingredient and just the final PPM readings. Wouldn't I need to know the reading after each ingredient to truly not have to measure?
What is the correct way to top off? I am finding mixed information ranging from just add water as needed and flush everything out after 3 weeks to never flush topping off with water and nutrients (test ppm).
Sorry if these are silly questions.
