My seedlings are currently in compost and are about 1 week old and looking good, they are about 3" tall both with 4 leafs. Now what am asking is at what stage can i transfer them in to my hydro's

Ive attached a sketch of my hydro and was also wondering at what level the nuts should be.

Oh and also another thing as well, my nut is 26-8-16 is this ok.
