Plants have lots of secondary growth, but not growing any bigger.

I am growing Carmelicious plants here in Colorado. They were jump started indoors for about a month, but that was stressful do to the fact that I had to use tiny little seed starter light. I made the mistake of starting them after ordering my grow lights ( supposedly 2-5 days shipping time became a month ) and had not alternative but crappy little light. I hardened them off prior to transplanting outdoors. Here is my question; The plants are presently about a foot tall, and the stems are bushy with secondary growth, but don't seem to be growing very fast compared to first sets of leaves. I';m a newb to this and wonder why, and what I might do to encourage quicker growth. Oh yeah, plants have been in the ground for two weeks.
