I think my tank doesn't get enough of something. Got a bit of thread/hair algae on not quite viable plants (trimmed or planned incorrectly).
Lilaeopsis brasiliensis doesn't grow very well, new shooters are a bit yellow/brown. So I started dosing Fe last week, but nothing changed, maybe my Fe ferts aren't so good, because I get cloudy water after dosing it. And also I have noticed small holes in leaves of Hygrophila polysperma. K deficiency? Can't be, tank gets 23ppm of K every week.
Any ideas, guys?
54L, 30w, 8h photoperiod, 8h co2 (drop checker is green), 50% water change/week
Ferts: KNO3, K2SO4, KH2PO4 (NO3: 24ppm/week, PO4: 2.6ppm/week, K: 23ppm/week) + Easylife Profito trace elements (contains K too) 3mls every other day. Also I was dosing Fe last week due to yellow lilaeopsis, 1-2ml per day of EasyLife Ferro.
