Changing Nutrients During Veg

I have some newly sprouted seedlings that badly needed nutrients in the reservoir so I mixed in 1/4 tsp. per gallon of Dyna Gro today. I've been wanting to switch to something else but haven't had time to go and get anything yet. Can I switch the nutrients to something else when I change the water? What problems may arise as a result of this change?

I think they should be fine...dont see why not. As long as you are completely changing the rez

this will be ok they can go into shock but thats if you do a drastic change
