Thank you so much for the help... Thats what I will do add water, I added three gallons to a five gallon start almost half diluted ...see what happens ...how soon will they recover after diluting? and only couple of leaves on plant towards the bottom like the first set of fan leaves are turning ...should i cut them off? or let them completly die? I am getting ready to change tank soon...I will use only half strength this time... I would like to change light cycle to see the sex soon I need a mom plant to clone from...can't afford seeds or the risk of bying them sent in the mail any sugg? Will the go through any additional stress when i change the light cycle? should I wait untill they are compl. healthy again first? Thanks again!!!! hope I can keep asking u questions as I go
