Quick question hydro users

Ok so i'm thinking for my first gorw to grow a auto strain and 3 other plants the same time just veg the other 3 when the auto is pulled. Ok question is < If i do that and when the auto blooms will it hurt using bloom nutes while they are vegin or what will it do?>

So you're going to grow out one auto then start 3 photoperiod plants with it so that the auto will be done when the others need to flower? Is that it? Are these dwc in different res? Aside from why you would want to do this, no all 4 can't be in the same res getting the same nutes when the auto is in late flower and the 3 are in early veg.
You may need to paint the picture more clearly.

its a 10 plant drip system res under the plants i wanted to start all 4 at the same time 1 being auto. -.- just wanted to veg the other 3 while the auto was doing its auto thing but no worries i'll just do the auto and waite
