It all goes back to the argument of flushing or not flushing. I personally dont, so I just keep going as normal - the one thing I tend to do as it is coming to a close is some extra top fertigating by hand just to get fresh water/nutes through the entire medium a good few times before I chop just to remove any salts that are hiding away out of reach of the drip/pers.
For example the last week would look like this if all my plants are finishing at the same time, so starting with a fresh batch of mix at the same EC (currently 1.6), go heavy in the mornings (20/30 after lights on), for example, if they were getting four feeds in the morning that would go to 6 or 7 with some additional hand watering to get the corners to make sure everything is saturated - keep an eye on the inbound and exiting EC and if there is no variance, down they come.
