It sure looks like the same stuff (GSA) I had on my anubia. So I am going to say yes you have some GSA. I only had it on like 3 of 15 leaves, my guess was those 3 leaves had more direct light. Nerite snails took care of that for me. Since then I've corrected my phosphate levels and it hasn't come back.
