It's just a first few days, I did start witch biobizz Coco Mix and I had all biobizz line products left from last run and I thought I can try them out with Coco Mix but I got cal/mag deficiency and I have transplanted them to biobizz light mix / biobizz Coco mix 50/50 and some extra perlite. I did add some fish mix for the first time but I think I won't add more for next few waterings.
