New in hydroponics what is the problem(s)

I would much rather have a ph meter. It is not possible to eyeball or guess your ph, and it very easily will drift out of the acceptable range in DWC... just look at the 50 fucking PH threads each month. I don't even use a ppm meter 95% of the time because ppm is much more predictable and has a much much wider acceptable range. Worse case, you can follow the instructions on the bottle at 1/3 strength and have no problems at all with the vast majority of strains (that I have grown).

If your roots are sitting in 4.6 ph water, it really doesn't matter what the PPM is and you will never know your ph is too low until your plant starts fucking up... and then it's a guessing game of is your ph too high, too low, is it fine and something else is wrong?
