la la la, I fear you shocked the lill girl when you transplanted. She will take a little while to catch up and may be a forever dwarf but that isn't all bad. I would get her some grow big, or another type of vegetative fert to encourage her root and stalk growth. Let her have some dry periods too so her roots will "search" for water and thus get a lill bigger in doing so. -- Oh wait you already moved her to flower??? Even still a lil grow big can't hurt. Also, keep her in a box with that cfl, a cabinet or some other confined space so you don't lose lumens.
I was transplanting my favorite girl and the soil was too wet and I ended up pulling off half her root ball. The poor dear! But she survived, she was stunted and showed preflowers early so I moved her into 12/12 about a month before my others and will still harvest a nice 1/2 oz off of her to enjoy while my others finish out.
