First time attempting to culture phytoplankton

[Lostoften]

I assume the one batch is bad, are the others looking on par? The orangish one and far left are nannochloropsis and the two on right are tetraseelmis.

These are at about day 16, with water doubled once and more f2 fertilizer added for new volume.
