For the past two weeks now my duncan can barely be seen fully open, and the stalk is turning a whitish color. I've moved it, and tried to put more/less flow on it with no avail. Can someone tell me what could be going on?
I would say if it turning white then your lighting is not sufficient. You could try spot feeding it to help until you can upgrade your lighting If all you have is PC lighting then that is not enough to keep a duncan.
I would say the spot feeding is what is doing it for you......I also spot feed mine and they grow a new head every 2 weeks to a month.....but the white is indicative of bleaching....
