I'm pretty sure that some excel should help with the BBA. Apparently it kills the stuff very quickly.
And i've read somewhere before that the holes in the plants are attributed to low levels of certain nutrients. Maybe up the dosage of Flourish and see what happens? Don't take my word for it, but maybe try a quick google search and see what comes up.
Hope that helps.
