Brown spots on phal leaves

[turock]

Thank you, guys, for the insight. I cut off the worst leaf and decided to watch it before cutting anymore. The spots did not grow.

The mealies were mostly tucked into the crevices between leaves, where they always like to hide. I followed your advice, cjm, and am seeing far less mealies and no new spots. I'm also wondering if they could be a strange form of edema, since I soaked my plant in the evening before repotting it.

Interestingly, I ordered some phals from a big wholesale nursery and noticed the exact same spotting on some of the leaves! Chocking it up to insect damage seems plausible. Also, I know those large nurseries use all kinds of chemicals and fertilizers, so I'm still suspicious that it could be a sensitivity to the insecticide.
