I have 4 GSCX going right now, in FFOF. I have watered with ph corrected water. I am waiting on my ppm meter to come in, should be today! But I need help with the process.
So I should be testing the water run off after watering, And based off that reading I should know whether or not they need to be fed?
My question is, how will I know based off the reading they will need nutes?
Thank you, anything helps!
