There is some debate among professional growers ove

some would say to do it only if there is excess salt or
mineral buildup, and some would say that if you are
using organic nutrients that you do not have to do it at a
If you are using mineral or chemical based fertilizers,
then flushing is a very good idea. It will help to prevent
salt toxicity in your plants. Additionally, if you start to se
your tomato leaves beginning to get brown spots, wilt,
curl downward, or even die, there is a great possibility
that you have excess salts and should flush immediatel
regardless of the stage of plant development or fruit set
If your system is an ebb and flood type, then it is more
likely that you would want to flush your system before
harvest in order to reduce the amount of mineral salts
