I've had a brief read (and I mean brief) about EI...
If I were to miss a water change how bad would it be??
I've never been one for weekly changes - more like 2-3 weeks...

This is the beauty of the method also, its flexible, in the beginning it mightnt be a good idea to miss a water change, as you get used to your doseing routine, but as time goes on you may find that you have to dose less, depending on the plants in your tank, as you become more experienced to the needs of the plants ie. they are not showing defficiencys, you will be able to skip water changes, its not written in stone that you have to do water changes each week, although it is recommended to reset the tank, but you will find that over time you will know how much to dose, this is the estimative part of the method and you will also know how much nitrate and phosphate the plants are consumeing, the guy who invented this method doesnt change the water in some of his tanks for 6 months, so it really depends one of the reasons you are doing water changes is to make sure you are not adding to much, you reset the tank, and then you build it up again.
You just make sure that none of the main fertilisers run out, but the ceilings for how much you can dose is quite high so its unlikely you will run out if you prepare correctly, so if you had to go away for a weekend or so it wouldnt matter as long as you knew none of the main ferts were going to run out.
Anyway i hope that makes some sense, if you think about it, if you have a planted tank and you go away for a week and you were only doseing regular liquid fertilisers, the chances are the plants will have defficiencys when you come back, because you probably unknowningly werent doseing enough in the first place, with the EI method you will learn exactly what your plants are consuming on a weekly basis because you will be doseing exactly the required amount, so basically you will have a very good idea of the timescale involved before you need to dose again.
Anyway thats what neighbours are for isnt it
Anyway i hope it makes sense.
