Dear Jeff,
 I use compact fluorescent lights and I top water when the soil is moderately dry.

Hi David,

Thank-you.  That was the relevant information I needed.  Like most sundews, Cape Sundews are bog plants and need their soil very wet.  If your soil is drying to any degree it would cause the symptoms your seeing.  You should always have the pot sitting in a shallow tray of water.  It doesn't need to be deep, and shouldn't be, but the soil should never be dry to the touch.  Our general rule is no more than 1/4th of the way up the pot.  Most sundews would have died already if their soil dried some, but D. capensis has thick roots that allow it to survive dry periods in South Africa.

You mentioned that your light is about 12 inches away.  A 20 watt CFL isn't a real big light, so you may need to get it a little closer.  Once you restore the watering, give the plant a couple weeks and see what the leaves look like.  If you're getting plenty of dew and red tentacles (provided it's not the "alba" form), the light is fine where it is.  If you're still not getting much dew and the plants is pale green, move it closer.  Go to about 8 inches away. Re-access it again after a week or two.  This is always what you have to do with artificial light since individual bulbs or lights can be so different.

Good Growing!
