Yes they are fine after 3 days. In an aero 100% of the nute uptake stops the very second the water is changed and plants don't store nutes. In their normal enviroment the storage is the medium in which nute levels are relative constant so they don't need nor have capacity to store up on stuff like that for much more than a short period of time.
You can see leaves starting to loose its color in 12 hours in an aero if you stave them. Coco and even more so soil needs to be flushed pure of nutes or as clear as possible before you actualy start starving the plants but you will bever be able to get them as "clean" as in a mediumless hudro/aero grow.

Yes the Amazon is an amazing system but needs a few tweaks mainly to keep the roots cool enough.
Its about 30*30 inches and takes 4, 8, 16 or 32 plants depending on what lid you buy it with. I grow with a 16 plant lid.
Price is about US$250 so very cheap as well.
There is a double lid version measuring about 60*30 inches also.
