Hi
I'm relatively new to the hobby of keeping aquatic plants in an aquarium.
I have a 120L/30 Gallon tank, with 3x18W T8 + 1x24W T5 lighting or about 2.5W/gallon. CO2 is provided by yeast fermentation, the Hagen Nutrafin system but my own "brew" that gives more CO2. I try to keep the CO2 stable by starting a new "brew" every 5-7 days. CO2 levels seem to be OK judged by a Cal Aqua Labs drop checker.
EI is the method I use to provide macro and micro nutrients. I'm using CMS+B and KNO3,KH2P04.
Substrate is just gravel, probably inert when it comes to nutrients.
I mainly have fast growing plants in my tank: Hygrophila polysperma, Limnophila sessiliflora , Vallisneria americana. All grow quite fast. Limnophila sessiliflora will overtake the tank completely in about 2 weeks if I don't prune it and remove new plants at each water change.
But I've always had problems with the Hygrophila polysperma. It was my first plant and I chose it as I read it was supposed to be one of the easiest plants to keep. The leaves will often be deformed or wrinkled and sometimes holes. Shortly after a leave has formed it will get pinholes that start to grow. In a few days the leave will curl. Sometimes the leaves will have white vains.
The water here is very soft. Probably abt 1dGH and 2-3dKH. I add GH booster to get GH up to about 5dGH as I've read that lack of Mg/Ca can cause pinholes.
I've attached images of the H.Polysperma showing what I describe. Any ideas what could be causing this?
