You probably do not need vegging nuts... Scotts had plenty of chemicals in their soil...

And as the group has mentioned.. start with a diluted nutrient mixture when you do feed.. you definitley do not want to over feed your plants...

What size pots are you using? It is not necessary to tranplant just because roots are coming out the bottom. But I like your attention to detail! : )

How any nodes do you have?
