Okay, wait until you actually SEE some roots. Then put them in small pots (3" is a good size) that have extra LIGHT soil in them. For my first transplant of new clones, I really like to add extra perlite to the mix so they don't have any chance of sitting there soggy.
Foliar feeding is when you mix up your fertilizer really weak and spray it on the leaves. Grow Big will work; just remember mix it less than the directions, add one drop of dish soap to the spray bottle, and wait until the little plants are showing roots to give them any food.
np on the patience; that's what I'm here for!
