Yep, that's exactly what I had to do. I run a scrog with each plant in a small pan of it's own and in it's own frame/screen (yay for modular). For normal feeding/watering it's excellent, but I had a few Kali Mists getting too much nutes and I had to flush them out using the turkey baster method.You need to place a catch pan underneath them and remove the runoff with a turkey baster. That is how I did it.
