Hey HydroLife,

When the plant starts to show new stem, node and leaf growth, that is the beginning of vegative growth. Looks from your last post that it has started.

The time to veg is not a critical issue, how long you do it is up to you (the benifit of indoors). You get to decide how big to make them, just remember the 2-3x rule, when you go to flower.

18/6 is fine for revegging, but so is 24/0. I have used both with success tho I haven't done it much recently, but when I have I've seen no real difference in how long it took.

Good luck with them and good growing. I'll look at your other thread when I get a chance.
