Default when to test using pps classic

I have chosen to use the pps classic system to run my new tank fertilizer regime. My question is at what time do I test the parameters of my tank? Do I do it befor I dose or after? Should I test at the end of the day or in the morning befor the lights go on? BTW, I've been dosing for 1 week and I can't believe the growth of the stem plants I've got it there.
