20g high low light plants not doing well

Hey all, I would appreciate some help with my planted tank. It has been established for about five weeks. Since then the plants have not been doing well.

The tank is a 20gallon high. The plants I have are java fern, amazon sword, cryptocoryne lucent, and an anachris. The only plant that is doing okay is the crptocoryne, yet it still is developing yellow/brownish spots. The java fern is black. The amazon sword leafs look thin and pale. The anachris is fine but it is a new addition. I previously had hornwort in the tank but that has since died.

For substrate I have caribsea eco-complete. For lighting I have the nicrew led and a 15w T8 TropicSun 5500k feature. The lights are on for a 12 hour period. I am also dosing Flourish Excel and aquavitro envy.

Any help would be greatly appreciated!

Yea, this sort of stuff can take a while. The leaves that have gone bad... there's usually no saving. Try to look for the new growth and see how that's doing whilst making sure that the existing stuff is not continuing in its downward trend. If a plant is ruined at the stem / rhizome level, sometimes, sadly, they may be too far gone to be revived :(
