I'm just dosing seachem flourish + seachem advanced. The light is 20 watt LED, I dose every water change, I water change once a week and 2 days about 33%,my pH is 7.4, unfortunately I don't have anything to measure my KH is 180, and my GH is 180 (not sure how accurate test strips are for this) my nitrates appear to be 10ppm.
I have yellowing leaves on some Lugia and curling leaves on a pogostemon stellatus octopus.
I've added some info
Thank you this is very insightful. How long do plants normally take to settle in? I've had mine for about 2-3 weeks.
