Well as some of you may recall from the past few months, I had purchased four windmills that are a year and a half old (I think). Anyways, over the summer I posted some pictures because I was conserned that they may be dying because they were getting brown spots on some of the fronds. Well now the situation has changed, I am at college now, and the palms are at room temp, and I put on the lamp sometimes, which I have a full spectrum light bulb in there, which I was told was good for mimicing the suns light. Well now I have noticed that some of the small fronds are turnings all brown, and shriveling in close. I tried to take a picture to show you, but they all came out pretty bad.. Any ideas how to fix this? My watering is when the soil seems dry enough, so I dont think its over/under watered.. Thanks!
