help neede on first grow!

hi guys, posted a couple of days ago with no luck.....

i have me seeds germinating at the moment and they will be ready to plant soon, i will be putting them into 1 inch rockwool cube which i will soak beforehand.

my questions is regarding nuits?
do i give my plants any at this young stage? or what age should i wean them onto it?

i know it has to be very weak at the start but just not sure of the finer details.

will be transferring into hydroponic bubbler once ready.... how old do they need to be before i do this?

thanks load in advance guys!

no to the nutes unless you see them droopy or turning colors, i do 1/4 strength till you see the roots coming out from the bottom of the rockwool.

I'm not sure as I soil but I read this before and it was VERY informative about bubblers from set-up on... https://www.rollitup.org/dwc-bubbleponics/234626-rosemans-diy-bubbleponics-tutorial.html probably just what you need.

you can put it into the bubbler when ever you want. You can just fill it with water. Then once the plant looks like it needs a little food start off at 2/4 strenght, usually around 300ppm. Then a few weeks later, once the plant is around 12" tall or so, bump it up to about 500ppm, keep doing this progression and let the plants tell you weather they like what your doing or not. Every strains requirements are a little different, si it is real handy to figure out how to read your plants accurately. Will help you with every grow you have down the road.
