Water+Nutrients- How long can it sit?

Hello,

Im pretty new to indoor growing... my plants are just starting to get their first leavs and im about to start feeding it... my question is this, when i add food to water, I need to make a minimum of 2L water to the solution... this leaves me with quite a bit of water left over after watering as i only have 2 young plants... so can i just leave the water sitting there with the nutrients and waiting for the next time i need to water the plant?

or does that affect the quality of the water?


Thanx

i norm make up 10ltr and leave it for days i stur it every day befor watering plants to get air into it but the propper way is to get an air stone and air pump.but ive had no problems done it for ages..

thanx mate. i got a fishtank airstone so i guess im sorted! but if u say it works the same without it then no worries there... i wont keep water sitting still for more than 4 days i suppose
