Whitish substance on S. t. Nelsoni - Help!
There appears to be growing on an offset of my S. t. Nelsoni - a whitish substance going up the stalk. I haven't really been overwatering this(I hope) knowing its sparsely watering rquirements, but this really has me concerned. It almost resembles a mold, not a solid growth but spotty going up the leaf, but I'm not sure and I am wondering what to do?? The plant is in a room with temps. between 65 to 70 degrees, I don't believe it is overpotted, only watered about every 3 or so weeks and them lightly. I cannot see any rot on the leaf. What should I do? Any suggestions would be appreciated. - Elaine
