I’m curious those who have successfully grown dark green tetraselmis phyto what concentration your using for the fritz 2 part fertilizer? The bottle says for 1 gallon of phyto it uses .5 ml each of part A and B. Everyone else claims to be using 1ml per 1 liter. Anyone have any experience on this subject? My phyto tends to go yellow after a few days and wondering if I’m under fertilizing.
