Hmm. That is a puzzle. Weak growth might indicate not enough light, or not enough nutrients. It sounds like your plant has those, but you might check if you can increase the light a bit (set the lights about 6 or so inches above the plant), and make sure that the plant is getting a balanced diet. Also, you might try increasing the temperature a degree or so (such as 21 C). You might also try increasing the humidity, such as setting it on a tray of pebbles 1/2 filled with water (make sure pot does not touch the water). Check for any pests that may be hiding under leaves or on stems, and watch for any spots or discoloring that may indicate a disease. Hope this helps!
