I was just thinking that myself. There's a few leaves towards the bottom that are burnt. I watered the plant one night and got water on the leaves - they were burnt the next day, so I'm more careful now & I haven't seen too many more. But please tell me what you think.

I've attached a couple of pics to show the leaves closer. I tried your links, but I get a forbidden message. Maybe my privicy settings. Sorry about the quality of the pics, but still working off my sh1t camera phone. Any comments would be helpful.
