Bro,

Those are some very healthy, very very ripe plants. THey are just growing slow, because, sorry man but its your lights.

Why are you running 2700K?

Get some 5500K or 6400K and see what happens.

The plants arent stretching because the lights are good and close like they should be...but you are essentially wanting more growth with a 42W bulb at 2700K.

At least, DOUBLE, the light you have.

Those 2700K just wont cut it if you want speed growth.

Be lucky however, because if those plants did take off, those lights wouldnt be able to hang.

Remember as your plant grows, so does the light demand.

Just saying,

...be very happy with what you have done. Nice healthy plants, short stems, good secondary growth...

and you have done it with 2 42W lights.......

that is something!!!!

But if you want them to bust out, you;re gonna have to give them a reason to reach...

You need to address the light issue.

THERE IS NOTHING "WRONG" with those plants of yours. In fact, quite the opposite is true.

Deal with the light issue....trust me thats all it is...

really good job.
