Dajerm, I just stumbled on the quote from Doc from Mar 4 that I was trying to quote. This in response to someone who shared your concern that nothing was happening.
"OK....now we're starting off on the right foot! The roots are much bigger than the foliage now....and we want to not only keep it that way, we want to emphasize roots.
Now is the boring, long wait between watering and drenches at this stage. Pay attention to the weight of the pot and as it dries out, put just a bit of water down the top so the roots start branching in all directions. About 1/4 cup is all you need.
The wet/dry cycle will encourage massive roots, short internodes, thick, strong stems and a good leaf/calyx ratio.
Perfect (to add) 1/4 cup and keep a 3 inch dry circle away from main stem
