Hi guys.
I'm at a loss and hope you can help! Something is wrong with my Hygrophila Siamensis. The leaves are turning a pale brownish colour. I've had plants of the same species look the same before and they've gradually turned pale and stopped growing. These plants were planted 5 days ago.
I fertilize with Tropica Specialised Nutrition and Tropicas root tabs (the substrate is coarse sand). I inject CO2 and they have moderate light according to Tropicas homepage. The light is on for 6 hours per day, since I'm trying to keep down an algae outbreak (I did a blackout a week ago, before I planted these plants. The algae appears gone. It was green hair algae and BBA.) and I'm changing 30% water every second day for the same reason. Looking around the internet I thought it looked like a Phosphorous deficiency, but I just tested the water (with a liquid test kit) and it said 2 mg/l. So plenty. I also tested Nitrate levels and got 25 mg/l. Again, plenty.
What do you think is going on?
