Dedi, after the week on water, has the nutrient in the reservoir turned color on you? If it is running clear, you should go back to using nutrients according to the schedule on your mixture. I would start off with half strength of what ever the recommendation is for this point in the grow, ie. week 4, week 6, week 8... You are nearing the finish line. For instance, with my Flora Series, in week 6, there are 9 ingredients for the full spectrum on the charts, the base three being Gro, Micro and Bloom. By week 9, that drops to only 5 ingredients and the schedule calls for NO flora Gro..
Now, if your nutrient reservoir is colored, I would do one more flush of a gallon in each plant, letting that drain to waste, turn off the recirculating pump and toss everything in that reservoir. Then mix up a fresh batch. If it is pretty clean, you could forgo the flush, at this point, this flush is not going to do any harm in any event.
It is going to take you a day to get a fresh batch of nutrient settled anyway. I just use tap water and let it sit overnight, even when I am just adding water to the reservoir I make sure that water has had a day to stabilize. So, mix up some fresh nutrients, give it another day on water, then flush if you want but make sure when you flush, that you are not pumping that back into your recirculating system... Then start feeding again, slowly for the first few days, as you see, it only takes 4 or 5 days for a difference to appear... So, in 4 or 5 days, if everything is looking good, start going back to full strength. You can add nutrients in stead of water, or speed up the process, make a 5 day period a week to play catch up on the recommended schedule... as this point in time, things are changing with that mixture anyway...
I plan for all my house plants, and right now I have well over 100 when you add all the new veggies for spring. I do not mix nutrients during the week, just to keep myself from going insane with feeding schedules... Then I feed on the weekends, flush, new nutrients, additives for some peppers to make them hotter, or tomato's to make them sweeter... Or when they get transplanted to the ground from a container... does not matter, everything gets food on the weekends, noting gets 'food' during the week... That same principle applies to my hydro as well as my potted plants...
