Hello I am in the middle of my first grow & I am going to be away for a little i was thinking about mixing my water (just pH adjusted) & my feedings (nutrients) & storing them in containers so that my help just has to water the plants & not a mix anything.. my question is does storing the feedings alter anything or will I be fine if I make them up each week for the week? This is what I am thinking about doing so it will be easier & they mess nothing up? Can anyone help?
