too much fertilizer can burn plants (from experience with grass ferts). IIRC, too much K leads to hair/spirogyra algae.
BBA...could still be a deficiency somewhere. I haven't been dosing ferts (way too busy lately), maybe a little light with the CO2, and I'm starting to see small tufts of it.
You could also try burying the root tabs deeper and/or adding more substrate up top.
