need help with flushing...never done it b4!!!

hi all, first grow and i need help learning how to flush, I am done in a week, and I want to flush, I am using eff and flow, and I filled my rez with pure water...

(1) DOES THE PH STAY THE SAME 5.8-6.3?

(2)I HAVE CLEAREX - HOW OFTEN DO I USE IT?


Any help would be appreciated...thx

WOW!!! seems like no one has grown before, anyone?????

come on! anyone?? really???

In my experience with flushing with Clearex, I flush only once about 2 weeks before harvest. Then water w/o Nutrients until harvest.

I'm in soil though. I'm pretty sure one Clearex flush is all you need.
