Damage to new leaf from mealybug...what to do?

[judith_arquette]

This poor Phal had really suffered under my care before I discovered this forum but thanks to all the help I've received here it began to recover putting out new roots (4 total now and all appearing to do well still) and a new leaf. I posted a pic in the beginner discussion forum and some sharp eyed members informed me I had mealybugs. I am treating as advised and only found one other (a week or so ago) and continue to diligently inspect it. The problem is that the new leaf is splitting, I hoped the split wouldn't get worse with the bugs gone but it is anyway and I don't know what to do...leaving it alone only seems to be making it worse :-/
