I have 2 Black Zebra Tomato plants, 1 black Cherry Tomato plant, and 2 Sungold Cherry Tomato plants. They are all in DWC buckets. My question is: How do you go about flushing them? I understand how it works with a plant that you harvest one time and then chop it down, but how does it work when you are dealing with a plant that continually produces fruit?

I am using Botanicare nutes. Do I just flush using something like sweet or clearex for 2-3 days and then harvest and then return to regularly scheduled nute-ing until the next round is ready?
