i have a problem with 2 of my vft's it seems to be that recently they have began to grow new leaves curled and of a fine sandpaper texture the leaves don't make it to maturity they die from the tip down at about 1 inch in size. any ideals on a reason why this might be happening. i use a 48" full spectrum grow light suspended over head approx 16 inches from the plants and a 48' cool White florescent approx 22 inches over head. they are in a 3 gallon round terrarium with a mixture fro **********.com i believe 60/40 peat/perennialite i have 2 terrariums and one has 8 plant's in it it seems fine yet this one with 2 both plants seem to be suffering this. there approximately 1 year old in there growing conditions and I'm using shop-rite bottled spring watter sodium free. there just recently out of winter dormancy also the leaves die off drown not black and thats different than in my other terrarium they die off black. 1 other thing i noticed is the tubing leading out of the tropicare humidity system that i use to keep them humid is stained with a whitish pattern the tube with air leading into it is unstained, any one with any info on possible cause for this problem with leaves curling an dieing would be most helpful.
thx for reading.
