These are my tank specs:
46 gallon bowfront
5.5wpg PC 10000K and 6700K
Soil underlayer below gravel
Fertilator says I'm adding (three times weekly):
N 12.7 (KNO3)
P 3.85 (Monobasic P sulfate)
Plus 5ml Flourish
Traces via CSM + B
I am also adding Kent Botanica Grow for Mg and Ca
CaCl for signs of a Ca deficiency that still persist
Moderate/heavy fishload
Pressurized CO2, between 10 and 25ppm depending on the time of day
The problem is that the plants are still not growing as well as I'd like. They do not get bushy, and they grow slowly. The Broadleaf stellata I ordered a month ago is in a well-lit location but has only developed two nodes with submersed foliage and appears to have stopped altogether. There is no algae to speak of other than the green spot that develops every few weeks on the glass.
Leaves of Hygrophila polysperma, Ludwigia glandulosa and Ammania senegalensis are still curling and stunting. Ludwigia inclinata will steadily lose its lower leaves until it develops floating shoots, and only these retain their leaves.
Am I adding too many ferts here? (I started to suspect it today, when the water got cloudy after my daily dose). Is too much P limiting N? I'm no biochemist
