Oh, and I'll probably get blasted for saying this out loud, but I use 1/4 nutes on my plants from the starting gate. I start my seeds and clones with water that is pH 6.0 and 1/4 strength nutes. I soak my rw in that, I water my infants with it, and I have that churning in my Aerogarden for clones.
I have only a little bit of experience, but this seems to work well for me. I have successfully germinated 3 out of 3 seeds, and rooted 13 out of 14 clones so I'd say it's at least working for me. If your baby is too slow, maybe she needs a little "boost".
