[What’s missing?]

Okay, good tips.  Thank you.

Yep, have easy green root tabs too.  I wonder if I am not feeding enough.  Is it so many plants that 4 pumps 2x per week isn’t enough to encourage growth?

[What’s missing?]

I have the following plants:

8 cryptocorne lucens

3 Amazon sword

5 baccopa

1 anubias barteri

1 Mayaca vandeli

2 dwarf tiger Lilly 

Several Java fern and Java fern wendelov

 

I dose easy green twice per week and add extra potassium twice per week also.  My plants are not taking off like I expected.  

Some of the plants are happy (Mayaca, anubias, Tiger Lilly) and others don’t appear to be (Java fern, baccopa, cryptocorne, Amazon swords). I planted four Amazon swords a month ago and they haven’t gotten bigger then when I planted them. I did lower my lights to 50% brightness to help cut down on algae but they still run for 12 hours per day.  Should the lights be brighter?  More fertilizer?

I test water weekly and am stable at 7.4ph, 0 ammonia, 0 nitrite, and I do 20% water change when nitrates go over 40ppm. I recently tested GH and KH and they came back fine. Same with phosphorous.
