Hi, I currently have CO2 being pumped to the tank and I am dosing with EI. All my other plants are doing great, MU, Indian Fern, Riccia and Hairgrass are growing exponentially, except the Amazon's. The leaves are developing holes, becoming transparent and brown patched. Do you have any idea of what it could be? I got a 120L tank, with 70w of light, 10 hours a day.
