My aquarium is very maturely cycled, having been set up for over 15 years. I know that ammonia is never a problem.the tank is under-stocked.
Even when fish die( I have amano shrimp who must consume them), I never have ammonia spikes, or rarely see any dead fish.
I never expected to have to feed the plants so often, but now I realize that as the plants grow larger, the tank requires more food to support the mass.
Java Fern loves Easy Green in my water, it grows to the surface of my 55...I have to trim and discard often.
I cannot grow bunch plants.( they slowly decline) Perhaps my nitrates are too low and the Java Fern/anubias are sucking up all the nutrients. I still manage to create interesting leaf contrasts/texture due to the many varieties of JF& A. With increased dosing, I will try to grow bunch plants again!
