Phal Newbie - Help!

[Mango2007]

I am a proud owner of two phallus (a white one and a purple one). I am new to the plant world and have been making sure to heed all the advice about not overwatering my orchids and to make sure they are not overfertilized. And to make sure they recieve bright indirect sun with proper air circulation. Whew!


My problem is with my white phal. Its petals are getting weird, bright, green spots on them. The spots are no bigger than a marker point.

Also the underside of the leaves have chew marks. The orchid came this way. The marks look like they are healing but they are still there. I think I saw a small, translucent-like bug crawling around in the phal's soil a couple weeks prior.


Any suggestions on how to help the phal? See images attached.


Thanks very much
