My plants dont seem to be doing very well,they are growing pretty good , but within a few days any new leaves seem to start turning yellow or brown and die,,,i give them liqiud ferts and co2 , but still the problems are there.The only plant that is healthy is my java fern ( the others are,watersprite,,,,hygrophila polysperma,,,and another type of hygrphila),,oh yes the lighting is 1 watt per gallon
