I have three 3gal. Fortunei's planted last summer.Two of them look fine except for brown tips.The one I am worried about is turning light green.When I planted all three of them they were all dark green,with no brown tips.I cant figure out why one is doing this(fading out)with brown tips.I always thought brown tips were caused by not enough water,and turning yellow or light green was caused by to much water.The brown tips didn't start till the weather turned cold.The one fading out started doing this at the end of summer.I gave it ES twice back during summer,with no change.It came with fertilizer already in the pot,so I haven't gave it any other fertilizer.What could be going on with it?I've watched it gradually keep fading since summer.Why would it have brown tips and fading fronds at the same time?It's like it's showing signs of not enough water and to much water at the same time.The other two are still dark green,they just have brown tips.Should I be concerned about them also?Trachycarpus palms are still a fairly new type of palm for me.None of my other palms are doing this,I mainly have Butia palms and Euro fan palms.Any help will be greatly appreciated.

Thanks,Randy.
