Plant fungus?

[chancesr]

Can I get some advice on what is growing on my plants? The white stuff was also on the glass. Are the black/green clumps bba? I’ve had that before but it was been several years. I’ve been battling elevated nitrates but parameters are better today. Thanks.
pH 6.6
Nitrites 0
Amm .25 (always looks like .25)
Nitrates 40-80 (was 160)
API test kit

The first picture looks like cyanobacteria to me and the second looks like bba.

I feel like the first picture is a mix of cyanobacteria and other some kind of brown algae. Second pic looks like BBA.
