hi i have hygrophilia growing in two tanks. the hygro in my 30 gallon is the one that has the curling leaves. the leaves at the bottom are straight and green same for the hygrophilia in the shade of the guggy grass. the leaves that are closer to the light seem to be affected. for a few months i have kept things constant. lights: dual t5HO (10000k and plant growth). they are set on a timer for 10 hrs C02: 3 ml of excel every day filter flow has been the same water changes every 2 weeks (it has no fish) temp: 82F in the day, 81F at night the only thing that has changed really is that for two weeks now i havent been dosing my esha plant food because it ran out. but the hygro in the 8 gallon tank is in the same conditions except it lives in low light leds. i dont dose ferts anymore because it ran out but the hygro in there is doing fine. could it be the lack of ferts or the high light?
