Would any of you be reluctant for any reason to switch to Jack’s in the middle of the grow? I’m about to flush salts out of FF HF during the 4th week of flowering and are considering switching mid-grow. I was using the FF Trio. @Myfriendis410
I’m following the 2.5g/3.5 gram Part A and part B plus 1.2g Epsom. Is there a need to add cal/mag with Jack’s + Epsom?
