I know nothing about that line, I only use fox farm, and for me I would have had to flush two times by this point one time before flowering and 4-5 weeks later. A lot of people on this site don’t flush unless problems are visible. I’m not that person I believe in flushing soil every 4-5 weeks like clockwork, my coco loco gets flush every 2 weeks no matter what. But that’s me and my method. I like getting rid of a problem before I even know it’s there. IMO it’s better for the plants less stress.
