So you had no issues other than you thought the plant was slow growing so you flushed it? What purpose does that serve?
You said in a different thread that it's been growing extremely slow due to cheap lighting. And someone also told you in a different thread that better lighting would help.
I'm just trying to understand why so many think flushing their plant is a good idea when it doesn't have any effect on the issue of inadequate lighting. Plus in another thread you stated you were growing in coco/perlite. You don't want to run straight water through coco.
