Fritz 2 part phyto fertilizer

[Ling_Thing]

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.

Not familiar with Fritz fertilizer. I suggest you add more fertilizer.

I don’t consider the jar on the right as dark green. However, that is the color that I seek. I harvest every 7 to 10 days.
