I recently changed my fertilizer a few weeks ago from Fluval Gro+ (which only contains micronutrients) to Easy Green. The reason for the change was because some of the leaves on my pants were whitening and I realize I was only providing micronutrients. However, my plants look much worse since the change. They aren't growing at all. Some of my plants have melted and many of the leaves of my amazon sword have turned clear and whithered away. Could this be a result of the fertilizer change? It also appears that more green spot algae is growing on the glass. My tank has been running for a year and I have fluval stratum as substrate. Water parameters are:
Ph = 7.2
Ammonia = 0
Nitrites = 0
Nitrates = 30ish
Kh = 2
Gh = 8
 
Can we get some pictures of the plants and 1 showing the entire tank?

In aquariums containing fish, you don't normally need the 3 macro nutrients (nitrogen, phosphorus, potassium) for aquatic plants.
  • Ammonia comes from fish food and waste is the source of nitrogen and the fish produce it continuously. Plants can also use nitrite and nitrate.
  • Phosphorus is used by plants to develop strong roots and thicken the cell walls. Most aquatic plants take their nutrients in via their leaves and have small root systems that don't do much except stop the plant floating.
  • Potassium is used by plants to produce flowers and fruits, neither of which most true aquatic plants produce (Vallis, water lilies, Aponogetons and a few other uncommon plants are the exception and produce flowers). But even these plants don't need a lot of potassium.

What sort of light is above the aquarium/
How long is the light on for each day?
How long have you had the plants for?
