Got a question for you gurus...

I am planning to use the bubbler method. MY question is: How do you fertilize the bubblers? Like after you do it the first time, do you just measure the nute levels then add more at some point or is it necessary to drain all the water and add fresh water and more nutes? Can you do this without an expensive digital meter? Usualy how often do you need to add more nutes?
