I did flush, then I had to repot because the canna coco is ruined if you do that come to find out. Flushing washes away some helpful bacteria and such that are naturally present. Everything is coming back around though. I am still in #5 and #7 Smart Pots and stepped up my watering schedule and that seems to have done it. THe S. Diesels are still a little sad, but they have new growth so I am remaining optimistic. The upside is my plants including the S.Diesels are only 13 days old and I literally have roots blowing out of my pots. The growth is crazy! I imagine at the rate they are going, I'll be flipping by weeks end.
