no real answers, but a couple of questions and observations.

1: why is your ph so low when the alkalinity is at 80ppm? It should be
closer to 8. Are you using co2?

2: change 50% of the water on a weekly basis.

3: Your nitrates should be nowhere near that high in a planted tank. If the
nutrients/lights/co2 are balanced most of your nitrates should be consumed
by the plants.
