So I have a Fluvial brand "Sky" LED light for my 55 gallon tank. It's seems very bright on some settings but its rated at less than 40 watts. I've read that you need 2 watts per gallon to grow plants. Does that rule apply to LED? I've planted some crypts, a couple of Amazon swords, several Java ferns and some anubias plants. I've seen some growth. I've been following the flourish fert schedule(trace, comprehensive, iron, potassium) for a week and have had root tabs down for 3 weeks. Some melting but new growth too. Am I okay? Thanks
