The bottom of the leaves had a white film on them and a dusty web like feel. I sprayed the leaves with insecticide soap and treated the soil. I found dead gnat on the leaves a few hours later and there was/are little pale bugs that look like 'spider mites' (e.i. google search images). I was told it might be overwatering. I water twice a week and wait until the soil is dry 1/4" down. Not sure about the container size 20 gal is a lot of soil for 2.5 foot plant?
