I agree with Nancy. Always err on the side of dry.
I like you gave it some systemic insecticide. I have had a lot of trouble with mealy bugs in the past until I started using some.
I have been using semi-hydroponics (s/h) for many (most really) of my caudiciforms with good results. There are lots of threads here that explain what it is and how to use the method. I recommend looking into the technique to see if it might be something to try.
Good luck with your plants.
