The first being that you do not want to let your plants become deficient in any nutrients be they macro or micro. Plants use different nutrients at different rates not only from week to week but day to day. If you do not change the resevoir, and add only water, after a short while you will not have the proper ratios of nutrients to be absorbed and your plants may become deficient.
The second reason being that algae will colonize and grow at an exponential rate, and after a week you may possibly begin to see slime and gunk forming around your pumps and clinging to your walls. This is averted by using H2O2 or the DIY Clear Rez formula on a regular basis, but if you are against these two it's best to change the water and if possible give the resevoir a short cleaning every change.
The last and my personal favorite is when using organic nutrients or additives. They stink. Short and simple they can get pretty rancid with all the beneficial bacteria having a microscopic shindig in your resevoir.
Now if you want to let your water go a little longer be sure to keep an eye on it. It's best to change it every week, but whatever works for you, works for you. Just use common sense and don't be lazy with res changes lol. Happy Growing ~23

A week at the longest IMO
Flush with fresh and ph'd water for anywhere from one pump to a couple of days, maybe every 2 to 3 weeks when you change the water.
A little bit of clearex also helps as well with the flush, maybe half strength maybe a little more. The clearex not only supplies the plants with carbs to assist in burning off the unused and stored nutrients in the roots and foliage, but also helps to break up gunk and clean your entire system. It is a great product. Another similar is Final Phase by AN. Both products will be a great help in the regular flushing and with your last week or two of final flushing. Happy Growing ~23

If you will let your nutrients bring tap water down to 5.5-6.0 you will not have to add pH down which is what causes excess salt build up.
Yes plants may use nutrients at different levels but I highly doubt they will use so much of one that it becomes deficient. Commercial hydroponic facilities never empty and change their reservoirs because they maintain there ppm's at an appropriate level.
I have one reservoir for my plants in vegetation and one reservoir for my plants in flower. Neither reservoir ever gets changed. I simply top up with 1 gallon of water at 1/3 strength nutrients each day and the nutrients bring the pH down to the correct level.
If you are inexperienced and have the money to burn it will not hurt anything to change once per week but I have found that when a system get established unless you contract some sort of bacteria, it will self regulate.

I change my res only in the last 3 weeks of flower. That's when I add my dry koolbloom to finish up for 2 weeks. Then a week of water
Question do you top off with plain water or nutes to keep your ppms up?
I change mine every 3 to 4 weeks. (mom and flower rooms). Also have 8 air stones

How long do you feed the 1st feeding for ,2nd,3rd? I feed 30mins,15,15. Ive seen some who feed for a 1h,1h,1h but those seem to be the ones who go back to dirt.

When in veg I only flood twice a day to promote root growth. U need to make them reach for the water. At a rate of fifteen minutes every 12 hours. If I feel them needing more ill add another flood. That's souly under my discretion.
Flower time comes around and I move my babies to there final resting place and flood her 4 times a day every 6 hours for fifteen minutes each. And that will be that.
