does my soil have enough nutes?

i moved my plant in a bigger pot.
i got new soil that is the same as the stuff i used in the beginning of my grow.
the soil is called black gold.
plants are about 7 inches tall and the stem is as thick as a regular sharpie.

do they need more nutes because they are bigger?
or should the nutes in the new soil be enough?

thanks!

I'm pretty new to growing, but from what I've come to understand it should be fine as is. You can ph the soil when you change the plants into different pots by running water through. And just give the plants nutes as indicated on the bottle. I started off with 1/4-1/2 of what was needed early in the plant(s) life and once it grew a bit, upped to the recommended dose. Dunno if that answers your questions but, uh, yeah....

U should be good togo for a week or two on just plain water
sheel tell u wen shes hungry
