Next big change was lighting. Went from three 13w cfl bulbs to three 23w cfl bulbs. This may be a bit too much but has had a positive impact. Two are 6500k and one on the right is 5000k. This will be interesting as I split up some species to be on both sides so I'll be able to compare them. Looks a little lopsided though color wise. Third change is I'm back to dosing, 1/2 EI daily, macros only, no micros, and 50% water changes twice a week. I like big water changes, but maybe smaller ones will help stabilize the parameters a little bit. I wanted to make sure the new plants that haven't rooted yet have access to nutrients till they are established.
