I've used FoxFarm Grow Big for vegetative growth on my seedlings in the past but HALF strength for the first two weeks. For example, My 10 gal DWC container calls for 2 teaspoons per gallon (20 teaspoons) so the first two weeks I would use 1 teaspoon per gallon (10 teaspoons). This will help those little babies establish some roots without over doing it. For the grow I'm doing now (which you can see the results for in my thread DWC Stealth Grow) I'm using CLONEX Clone Solution, which is specifically made for Clones and Seedlings.

Hope this helps out a bit. Basically you don't have to add a bunch of different nutrients and get all fancy, the little ones need very little to be happy and start growing. Light, air and water are the main things of course.

Happy Growing Y'all:thumbsup:
